[Mesa-users] Issues finding acceptable model when rezoning model

[Frank Timmes]

not in my experience. perhaps this a first bug report on delta_mesh_coeff being broken generally (see https://docs.mesastar.org/en/latest/contributing.html#bug-reports ), but its difficult to assess or suggest alternatives for increasing the spatial resolution without at least sharing one's inlists.

I had it set to 1.0d0 and I was only able to drop it to about 0.8 before I encountered my error. The error is the typical dt < min_timestep_limit, stopping because cannot find acceptable model. For reference, my timestep is set very low for the purposes of this simulation (8.76 hours).
