[Mesa-users] a mesh point removal

[Farag, Ebraheem]

Hello Natasha,

Yes, you can call "remove_surface_at_cell_k". This is a starjob option. Alternatively, see $MESA_DIR/star/public/star_lib.f90: "subroutine star_remove_surface_at_cell_k". You can call this subroutine in your run_star_extras on the fly to remove a surface cell. Call it with k = 2.

Subject: [Mesa-users] a mesh point removal

Hi all,

Is there a subroutine in MESA that can be called to remove a specific mesh point, along with all associated quantities? Specifically, I’m interested in fully removing the outermost surface mesh point. While I know how to manually update q, dq, m, and dm, xmstar etc (everything related to their values updated) it would be helpful if there is a built-in subroutine that handles a one-index shift for all relevant variables consistently (life would be so much easier if the counting would have started from the center).
I deal with mesa 23.05.1, or 24 versions.

Thanks,
Natasha
