bcf06ab Finished the compressible Stokes solver for TALA. Two non-dimensional parameters are added: "dissipation_number" and "gruneisen" under the Solver component. One can use the original incompressible solver by setting "gruneisen=0". The code will treat this as "gruneisen=infinity". Setting non-zero value to "gruneisen" will switch to compressible solver. One can use the TALA solver for incompressible case by setting "gruneisen" to a non-zero value while setting "dissipation_number=0". This is useful when debugging the compressible solver. Two implementations are available: one by Wei Leng (U. Colorado) and one by Eh Tan (CIG). Leng's version uses the original conjugate gradient method for the Uzawa iteration and moves the contribution of compressibility to the RHS, similar to the method of Ita and King, JGR, 1994. Tan's version uses the bi-conjugate gradient stablized method for the Uzawa iteration, similar to the method of Tan and Gurnis, JGR, 2007. Both versions agree very well. In the benchmark case, 33x33x33 nodes per cap, Di/gamma=1.0, Ra=1.0, delta function of load at the mid mantle, the peak velocity differs by only 0.007%. Leng's version is enabled by default. Edit function solve_Ahat_p_fhat() in lib/Stokes_flow_Incomp.c to switch to Tan's version. 09 August 2007, 22:57 UTC

dea4ac2 Setting solver.ic.tic_method=-1 will read the temperature field from old velo files. 26 April 2007, 00:44 UTC
55a6bec Append timestep to the checkpoint filename. Write/read timing information correctly. 25 April 2007, 20:17 UTC
6962d60 Clean up the old way of tracers/composition restart. Setting solver.ic.restart=on won't read the *.tracer.* and *.comp_el.* files anymore. Setting solver.tracer.ic_method=2 will read the old *.tracer.* files as before, but the composition field will be calculated according to the tracers, not read from the *.comp_el.* files. The parameter solver.tracer.reset_initial_composition becomes obsolete. 25 April 2007, 19:30 UTC
12e75b9 Fixed a bug in tracer setup 25 April 2007, 19:03 UTC
f8acab5 Implemented writing and reading (binary) checkpoints. The checkpoint file is called [datafile].chkpt.[rank] and is outputed with an interval of controller.checkpointFrequency. Before writing the checkpoint file, the previous checkpoint file (if exists) is renamed to [datafile].chkpt.[rank].bak. To read back the checkpoint file, set solver.ic.restart=on. The old checkpoint file, [datafile_old].chkpt.[rank] will be read in. The timestep information is stored in the checkpoint file. There is no need to specify solution_cycles_init, as the old way of restarting. The old way of restarting (read in temperature from the velo files) will still be available through solver.ic.tic_method=-1. (To do.) Several things to do: clean up the old way of restarting tracers/composition, documentation, does mat_control need checkpoints? 24 April 2007, 22:16 UTC
