Revision 13492bf45888f5b55d194881d9da8b9040b9984e authored by Thorsten Becker on 29 August 2007, 00:51:20 UTC, committed by Thorsten Becker on 29 August 2007, 00:51:20 UTC
lib/Instructions.c by hand, which I hope I did properly. Here are my changes: - renamed CONTOL structure members ORTHO and ORTHOZ to CITCOM_ORTHO and CITCOM_ORTHOZ Those were never used and conflicted with definitions in GMT gmt.h - Added a higher frequency heat flow output option like so: write_q_files=1 # option to write heat flux to files qt.dat and qb.dat # at intervals smaller than storage_spacing (0) - Added the capability to read in initial temperatures from netcdf grd files, if -USE_GGRD is used. Lot of options, like so: # # read initial temperature conditions from grd files (default values in parentheses) # tic_method=4 # read initial temperature from netcdf GRD files (off) ggrd_tinit_scale_with_prem=off # scale the temperature with PREM densities (off) ggrd_tinit_scale=1.0 # scaling factor to apply to read in scalars f (1.0) ggrd_tinit_offset=-0.5 # offset, T = f * scale + offset + tm (0.0) # where tm is the mean between top and bottom TBC values # if the bottom is flux, will use 1 for bottom TBC value ggrd_tinit_gfile="../../data/tomography/s20a_smean_new_age/t" # prefix of grd files, will # try to read t.1.grd, t.2.grd ... t.n.grd # where n is the number of layers in the depth file ggrd_tinit_dfile="../../data/tomography/s20a_smean_new_age/tdepth.dat" # file with layer depths in km from bottom up ggrd_tinit_prem_file="../../progs/src/hc-svn/prem/prem.dat" # PREM data file ggrd_tinit_override_tbc=on # override temperature boundary conditions (off)
