Keep _amr.max_level = 0_ and then I want to **map** data from the coarse grid to finer resolution grid for computation, but I'm new here and I'm trying to do...

My case file is EB_FlamePastCylinder (_PeleLM/Exec/RegTests/EB_FlamePastCylinder_), and I change the boundary from _Interior_ to _NoSlipWallIsotherm_, the others remain the same. I am asking for your help to diagnose the issue. ...

YES, IT WORKS. Thanks a lot dear **_esclapez_** and **_drummerdoc_** for your reply. I have another question, can the **_boundary of EB_ be set to _NoSlipWallIsotherm_**? Thanks again.

I'm using an old version of PelePhysics. Yesterday's question was answered, but when I executed **./make-mechanism.sh**, a new error: **UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 36: ordinal...

[here](https://stackoverflow.com/questions/10561923/unicodedecodeerror-ascii-codec-cant-decode-byte-0xef-in-position-1) is very helpful to me, the **header and .cpp** file have been successfully generated, thank you very much!!!

I found it and tried it, it works great! ! ! Thank you.

If they can be got it, it's definitely the best. Otherwise, I want to get the diffusion coefficients and reaction rates of the species, and then get the parameters that...
