06cd90c Eric Heien development branch 08 July 2011, 23:14 UTC
56f6015 Fixed typo for anisotropic stress computation. 21 March 2011, 00:13 UTC
a0153f3 Added a flag force_iteration which if on (off by default), will enforce an iterative solution to the velocity fields even if linear rheologies were chosen. This is useful for debugging/robustness tests. 22 February 2011, 04:13 UTC
966fcd8 Modified storage of anisotropic viscosity files. Those are now 18 February 2011, 19:45 UTC
7ea7b1d Improved vtk output, still for Dan to test. 14 February 2011, 05:45 UTC
446b149 Aedded the actual files because I didn't know how to link from CitcomCU. Those are didentical 12 February 2011, 05:30 UTC
7a6fa87 12 February 2011, 05:20 UTC
1cfc861 Removed the srand() call that seemed like a good idea (rev. 17175) but screwed up tracer-based runs with large number of processors (12x3x3x2). Weird, but oh well. Someone advise why this didn't work? 08 February 2011, 04:06 UTC
9086505 Added one missing line for anisotropic viscosity init. 07 February 2011, 19:00 UTC
8507b40 Reversed, temporarily, the use of nearneighbor because it makes it easier to compare model computations with previous versions. 07 February 2011, 00:32 UTC
12ac22c Fixed typo that was introduced in 17555 and made temperature field assignment apparently screwed up. 06 February 2011, 23:57 UTC
4fb41eb Backward compatibility of neglect of both divergence and pressure for convergence checks. 05 February 2011, 23:45 UTC
c21beb1 Temporarily moved velocity gradient computation to ensure compilation. 04 February 2011, 05:03 UTC
9c045e8 Uptdated prototypes file. Fixed a few compiler complaints. Made sure that atemp is always set in Viscosity_structures, making mat_control > 0 feasible, not just 0 or 1 03 February 2011, 21:06 UTC
8dcea68 Forgot some functions, not sure why the linker didn't complain previously. 03 February 2011, 17:11 UTC
93f3131 Futher synchronization with CitcomCU anisotropic viscosity. 02 February 2011, 01:09 UTC
4d1c25b Trial synchronization between CitcomCU and CitcomS anisotropic viscosity. 02 February 2011, 00:30 UTC
2f2115e Added parentheses for logic statements as per compiler suggestion 26 January 2011, 00:14 UTC
2598655 Checking in Shijie Zhong's revised Advection_diffusion routine. 19 January 2011, 21:00 UTC
452a6d7 Added support for non-interpolated grd input. 29 December 2010, 20:47 UTC
b6fe6e9 Minor fixes for compile, still hunting for convergence problem. 22 December 2010, 21:53 UTC
dc5cd22 Reverted to separate horizontal_bc routines for regional and full. the former has a check for ROW==E->lmesh.NOZ[level] && E->parallel.me_loc[3]==E->parallel.nprocz-1 while the full version has ROW==E->mesh.NOZ[level]) && (E->parallel.me_loc[3]==E->parallel.nprocz-1) ) 08 December 2010, 21:06 UTC
4ea70e2 Reverted the rowl adjustment since it didn't fix the problem reported by Dan. 08 December 2010, 20:14 UTC
df821c0 Added definition of TRUE (1) and FALSE (0) in case undefined (was defined for GMT/ggrd compile before). 08 December 2010, 18:43 UTC
cf7495e Addded a test for top or bottom nodal row back into horizontal_bc (earlier moved from Regional_boundary_conditions and Full_boundary_conditions to BC_util.c) to see if this helps fix a bug reported by Dan that I could not reproduce in the non-pyre version. 08 December 2010, 00:54 UTC
9bc8fb6 More accurate computation of element coordinates in anisotropic part. 12 October 2010, 06:36 UTC
010b460 Augmented G matrix with anisotropic computation, may or may not be a good idea. 24 September 2010, 03:35 UTC
cbf9149 Missed one routine. 15 September 2010, 10:40 UTC
1e59dd6 Suggested use of general prototypes Retired N>3 matrix determinant functions (because they caused compile problems) 15 September 2010, 10:36 UTC
0c84e99 Read in sdepv_misfit regardless of rheology. 14 September 2010, 01:08 UTC
bf59b6b Added option to start with isotropic viscosity during first anisotropic iteration. 13 September 2010, 14:07 UTC
a112ea8 Forgot part of the rotation matrix, minor fixes else, still experimental. 13 September 2010, 12:01 UTC
ab35881 Made sure current version compiled nicely without additional flags. Anisotropic viscosity is set up more flexibly. 13 September 2010, 07:13 UTC
b5d6c30 Made sure that viscosity prefactors get assigned for material dependent viscosity only (TDEPV = off) 07 September 2010, 07:05 UTC
a345eef Added random number generator initialization to ensure exact reproducibility of all runs, including those with tracers. Earlier reported solver issues might be related to our cluster, at least all revisions seems to give the same answer now. 07 September 2010, 02:22 UTC
1cf026d Checking in current version because of need for debugging. Revision 17172, compared to (presumably) 17153 give strange multigrid convergence behavior. Checking why that is now. 07 September 2010, 01:40 UTC
1efa65c Trial implementation of anisotropic viscosity. 06 September 2010, 05:20 UTC
4ecc25c Added support of multigrid solver in Exchanger. Lifted the solver assertion in Coupler. Cookbook9 can be converted to multigrid solver once appropriate parameters (*solver.mesher.levels=2 and *solver.vsolver.Solver=multigrid) are added. However, the embedded solver will converge incorrectly. Setting esolver.vsolver.accuracy=6e-3 seems to fix the problem. 30 August 2010, 20:41 UTC
bd28b8f And a typo fix. 25 May 2010, 02:47 UTC
f71b317 toplayerbc > 0 will now assign BCs for all noes with r >= toplayerbc_r, which defaults to 0.984303876942 i.e. 100 km depth. (Still experimental.) 24 May 2010, 18:00 UTC
ed7e8ae Improvements for internal BCs. 12 March 2010, 00:41 UTC
b732e74 This logic should make more sense for internal BCs, but still testing. 10 March 2010, 19:55 UTC
8a2427e Experimental implementation of a single node layer for internal boundary condition assignment, assigned if toplayerbc < 0, to nodes at layer noz+toplayerbc, but only for the top level multigrid, for now. 10 March 2010, 19:38 UTC
70a834f Fix a misleading comment 26 February 2010, 21:04 UTC
4ff7faa Fix an error when running autoreconf -i 02 February 2010, 23:41 UTC
f5834c5 Changed internal variable name for use_se_smoothing, as per Eh's suggestion. 01 February 2010, 19:43 UTC
2a3b029 Added old CitcomS element -> nodes -> element viscosity smoothing with new use_ne_visc_smooth parameter, default is off. 29 January 2010, 14:48 UTC
8bb44b5 Added pyre input for the new parameters added in r16138. 21 January 2010, 21:23 UTC
3ad8c8c Replaced fixed accuracy setting. Bug reported by Rob Moucha. 21 January 2010, 21:22 UTC
c4154bc Added opendx macro to visualize opt (e.g. composition) fields. This fixed Issue99. 21 January 2010, 20:11 UTC
0dc0383 Preliminary support for the absolute tracer method. Only tested with one flavor, reading in from a file, and the initial volume of the tracers is HARD-CODED! In addition, the code automaticaly truncates the composition to one, although this should be a switch for the user to specify. 17 January 2010, 01:19 UTC
110bd1c Implementation of two, perhaps entirely unnecessary features, in search of why certain prescribed velocity models do not converge like they should. - allow for each inner loop solution to have a higher accuracy than the outer, Uzawa loop. This is set by new parameter "inner_accuracy_scale", which pre-multiplies the inner accuracy (imp) setting (defaults to unity) - remove any rigid body rotation at each Uzawa iteration step. Parmaeter "inner_remove_rigid_rotation", by default off. For this, I also added an experimental routine assign_v_to_vector() in order to reasign the V velocities to the U solution vector after removing the net rotations from V (how is supposed to work for the regular operational mode?) 16 January 2010, 02:47 UTC
33e0d0b Replaced TRUE and FALSE. Added function prototypes. 09 December 2009, 02:25 UTC
ef97d2c Added two boolean parameters for controlling convergence criterion: check_continuity_convergence (default=on): include div/v in the criterion. check_pressure_convergence (default=on): include dp/p in the criterion. Retired the parameter: only_check_vel_convergence. 08 December 2009, 21:44 UTC
7efded4 removed unused variables in Drive_solvers.c 08 December 2009, 21:43 UTC
e829bf5 Merged solve_constrained_flow_iterative_pseudo_surf() with void solve_constrained_flow_iterative(); assemble_forces_pseudo_surf() wi Removed used python bindings in module/stokes_solver.c 08 December 2009, 21:43 UTC
0c6082f Truly apply internal boundary conditions on horizontal surfaces for E->mesh.toplayerbc > 0 (default, of course, 0) 08 December 2009, 17:19 UTC
025e452 Modified handling of internal BCs, as per Eh's suggestion, now handled in a separate function. 04 December 2009, 23:16 UTC
21c984f Removed metioning the version number in README. Added the url of the manual. 04 December 2009, 21:57 UTC
e20fdfc Suggested unified treatment of horizontal_bc (moved to BC_util) for review by Eh Improved handling of grd-read velocity and traction boundary conditions. 04 December 2009, 17:44 UTC
45144ae Temporary fix for regular operations, for Eh's review. Ggrd assignment still needs tending to. 04 December 2009, 02:33 UTC
1f61de1 Experimental implementation of internal stress or velocity boundary conditions. As of right now, toplayerbc > 0 (default = 0) will assign the surface boundary condition to all nodes within the first toplayerbc layers. If BCs are assigned from file, this will only work for the grd method, not the regular file I/O. 03 December 2009, 23:51 UTC
adf8b19 Exit criterion for incompressibility iteration allowed for velocity and pressure convergence at finite compressibility > accuracy. Changed criterion to loop while (convergence < 2) OR (compressibility < imp) Please review Also modified the sloppy iteration branch, where pressure isn't checked. 21 November 2009, 00:15 UTC
5f38ecb Clean up #include 20 November 2009, 21:58 UTC
aca8438 Fixed two minor errors 20 November 2009, 21:58 UTC
0ba4cb4 Created a new array E->sphere.gr for the radii of all layers. This makes gather_r() obsolete. 19 November 2009, 23:11 UTC
7ae00fb refactor viscosity definition 19 November 2009, 23:09 UTC
8e9f046 'localhost' can abbr. as '-' 19 November 2009, 23:08 UTC
09cea7d Changed defaults for z_410, z_lmantle, z_lith to more Earth like parameters. Does this break any tests? 14 October 2009, 18:26 UTC
3ee0608 Fixed typo. 13 October 2009, 16:37 UTC
0271108 z_layer needs 4 elements 08 October 2009, 18:01 UTC
4e0b2f4 added only_check_vel_convergence to pyre version. 07 October 2009, 04:39 UTC
4b0faab Modified handling of ggrd_mat_control, > 0 will select all layers above, < 0 will select individual layer == - ggrd_mat_control 06 October 2009, 18:48 UTC
ee214e5 Add pyre binding of z_layer, r_grid_layers, rr, and nr. replace MAX_MAT with CITCOM_MAX_VISC_LAYER. 05 October 2009, 19:06 UTC
2622434 Refactoring z_layer input validation. 05 October 2009, 19:05 UTC
599ab80 Dealing with tracers that belong to the current processor but cannot find its element. When itracer_warning is off, the code will ignore the lost tracers. When itracer_warning is on (default), the code will abort. 05 October 2009, 19:05 UTC
a3b2b41 Experimental traction surface BC from grds. 02 October 2009, 23:16 UTC
11d52ac visc_layer_control: allowing each radial layer has its own viscosity parameters When "visc_layer_control" is true, the file "visc_layer_file" is read in. The format of visc_layer_file: param_nameA Aval_1 Aval_2 ... Aval_nel param_nameB Bval_1 Bval_2 ... Bval_nel . . . The first line is assigned to the basal layer (CMB), and the last line to the surface layer. Note that each parameter has nodez-1 values. 28 September 2009, 20:08 UTC
e407de4 clean up unused viscosity variables 28 September 2009, 20:05 UTC
bb0c1ea Fixed a bug in pseudo free surface, reported by Robert Moucha. 28 September 2009, 20:05 UTC
f173a47 remove duplicating prototype declaration 28 September 2009, 20:04 UTC
5f0f67f Added pyre binding for write_q_files 03 September 2009, 17:24 UTC
3024d9f Added a warning message about tracer + coupling 03 September 2009, 17:24 UTC
37b376d Forgot one valid check for Uzawa iterations. 25 August 2009, 19:54 UTC
ba42e48 Ensure that Uzawa solver does not converge if low level, MG solver does not yield a valid solution. 25 August 2009, 17:31 UTC
57faf89 test implementation of steady state strain-rate weakending via PDEPV psrw=on parameter. 21 August 2009, 20:32 UTC
4b24572 Add Murnaghan's integrated linear EoS as reference_state=2 11 August 2009, 17:48 UTC
9157604 Add gather_r() to gather all radial coordinates 11 August 2009, 17:47 UTC
a0d609e Adding augmented Lagrangian component of stiffness matrix in cbf topo 11 August 2009, 17:35 UTC
e5a69cd The function collect_terms() turns out to be quite expensive (over 70% according to gprof). Perform it once per level, caching the result. 04 August 2009, 01:45 UTC
6957a07 Fixed the remaining bug in n_assemble_del2_u(). Glancing at "global_defs.h", I had assumed that VBX, VBY, and VBZ were defined in the natrual way: #define VBX 0x2 #define VBY 0x4 #define VBZ 0x8 I.e., "0x1 << doff"... but today I looked at it more closely; Y & Z are reversed!!! #define VBX 0x2 #define VBZ 0x4 #define VBY 0x8 With this fix, the CUDA multigrid solver seems to work correctly. 29 July 2009, 20:16 UTC
6a06281 Ensure debugging output for ggrd_vtop mixed BC if more than one CPU with depth is used. Previous check in of precise_strain_rate=on mode seems to be OK, stress, geoid, and dynamic topo output (for cbf topo off) have been tested. 29 July 2009, 04:05 UTC
b9278a2 Experiments show that using a block size of 1 leads to poor performance. Using the recommended minimum of 64, gauss_seidel_0 and gauss_seidel_1 are about 3x to 4x faster. 28 July 2009, 01:00 UTC
b500001 Fixed stupid reduce bug that affected several routines. (This is what I get for coping & pasting example code without thinking.) Now the only remaining broken routine is n_assemble_del2_u(). 27 July 2009, 23:44 UTC
9a97294 Wrote two new versions of gauss_seidel_2() -- neither of which is very parallel. Both produce similar wrong answers. 25 July 2009, 02:48 UTC
fb1101a This version of precise strain-rates may now be worth testing out. 24 July 2009, 01:03 UTC
