This folder contains all the files needed to run the Planetary Evolution Model (PEM). run_pem1: Bash file that runs chained simulation of PEM. The number of PCM simulation in between each PEM run is setup via "nb_GCM_call" variable. It is running using the run0 file from the Mars PCM. The number of PEM simulation to be done is setup via "num_PEM_now" and "num_PEM_end". The path to source the arch file needs to be adapted, as well as the number of MPI/OMP. The resolution and the planet type needs also to be adapted. The header correspond to the IRENE calculator, and should be changed for other machines. run_PEM.def All the possible parameter of PEM (read if conf_pem.F90). Nees to be included in run.def with INCLUDEDEF=run_PEM.def ob_ex_lsp.asc File containing obliquity, excentricity and ls of perihelion form laskar in Martian year. To run the PEM you need to change in context_lmdz_physics.xml the line enabled=".false." to enabled=".true." of Xdiurnalave
