PEM:
The management of files during the chained simulation of PCM/PEM runs has been simplified:

  • "tmp_PEMyears.txt" and "info_run_PEM.txt" have been merged into one file called "info_PEM.txt";
  • "reshape_XIOS_output.F90" now creates directly the "data_PCM_Y*.nc" files needed by the PEM;
  • where it is relevant, 'GCM' has been replaced by 'PCM' in the files naming;
  • the files in deftank have been updated consequently.

Following r3095, 'iniorbit' is now a subroutine of "planete_h.F90".

1This folder contains all the files needed to run the Planetary Evolution Model (PEM).

3# launch_pem.sh:
4  Bash script file to launch the chained simulation of PEM and PCM runs.
5  The user has to specify:
6      (i)   n_earth_years -> the number of Earth years to be simulated in total;
7      (ii)  nPCM -> the number of PCM calls between PEM runs (usually nPCM=2);
8      (iii) exePEM -> the name of executable file for the PEM run;
9      (iv)  exeReshape -> the name of executable file for the data reshaping task with XIOS.
10  The path to source the arch file should be adapted to the machine.
11
12# exePCM.sh:
13  Bash script file to run the PCM with a SLURM job. The name of the PCM executable file should be adapted. The header corresponds to the ADASTRA supercomputer and should be changed for other machines.
14
15# run_PEM.def
16  All the possible parameters to define a PEM run (read in "conf_pem.F90").
17  It needs to be included in "run_PCM.def" with "INCLUDEDEF=run_PEM.def".
18
19# obl_ecc_lsp.asc
20  File describing orbital parameters for Mars from Laskar data. It contains the Earth year and the corresponding obliquity, eccentricity and Ls of perihelion.
21
22# modify_startfi_orbit.sh:
23  Bash script file to modify orbital parameters in the file "startfi.nc" (obliquity, eccentricity, Ls perihelion and possibly initial Ls). They should be consistent with Laskar's data in "obl_ecc_lsp.asc" to start a chained simulation at a specific date.
24
25# concat_diagpem.sh:
26  Bash script file to concatenate along the variable 'Time' all the "diagpem.nc" files of the PEM into one NetCDF file. 'Time' is re-indexed with the numbering of Martian years simulated by the PEM run.
27
28Note:
29  To run the chained simulation, be careful to have:
30      (i)   the xml files for XIOS. There should be "iodef.xml", "context_lmdz_physics.xml", "file_def_physics_mars.xml" and "field_def_physics_mars.xml" which can be found in the deftank folder. In "context_lmdz_physics.xml", the line for Xdiurnalave should be activated (enabled=".true.");
31      (ii)  the usual def files to run the PCM. "run.def" should be renamed in "run_PCM.def";
32      (iii  the starting files ("startfi.nc" and "start.nc"). The former can be modified by "modify_startfi_orbit.sh";
33      (iv)  some optional files. For example, "diagfi.def" and "diagpem.def".
