leapfrog_nogcm.F @ 3020

Last change on this file since 3020 was 2108, checked in by emillour, 6 years ago
Follow-up of r2016 commit of nogcm main program: adapt leapfrog_gcm so that it does not explicitely depend on "phymars" and thus causes compilation issues when using other physics packages. EM
