[mesa-users] A problem in making planets

[Songhu Wang]

Hi all,

These days, I try to conduct some planetary evolution work using MESA,
although most of my previous work focus on observations.
There is a developed demo case, named 'make_planets', in star/test_suite in
released mesa directory (I use mesa-r8845).

In this demo case, we need three steps to build and evolve a planet:
1. create an atmosphere envelop (inlist_create)

2. insert a core (inlist_core)

3. evolve (inlist_evolve)

Now, I have a problem in the first step.
In the demo case, they try to build a 2R_J planet (radius_in_cm_for_create_
initial_model) with 1M_J (mass_in_gm_for_create_initial_model).

I can run this demo smoothly, but when I try to use 1R_J as initial planet
radius (radius_in_cm_for_create_initial_model), I found no matter what
initial planet mass I choose, I can not run the code anymore.

The reported error is attached.

Can you give me some suggestions?


Thank you,
