[Mesa-users] Problem in .../mesa-r15140/star/1M_pre_ms_to_wd example

[Rob Farmer]

Hi,
If you look in the rn script you'll find:

# check if can skip the slow climb up the red giant branch
if [ -z "$MESA_RUN_OPTIONAL" ]; then
   cp standard_start_he_core_flash.mod start_he_core_flash.mod
else
   do_one inlist_to_start_he_core_flash_header start_he_core_flash.mod
LOGS_to_start_he_core_flash
   cp start_he_core_flash.mod standard_start_he_core_flash.mod
fi

When we are testing mesa we skip certain phases of evolution for certain
stars to speed the testing up. In this case we skip the helium burning
phases of the star's life, which is why you get a gap. If you set the
environment variable:

export MESA_RUN_OPTIONAL=1

it will run the missing phases.
