<div dir="ltr">Nick, is chombo truly necessary for your needs? I am curious!<br>
<br>
I would recommend that if you're interested in using an MHD AMR code that utilizes chombo to try AstroBEAR (<a href="https://astrobear.pas.rochester.edu/trac/" target="_blank">https://astrobear.pas.rochester.edu/trac/</a>). There are probably others... but
aside from FLASH, this is a code I know. Perhaps others can recommend too.

<div>Otherwise, I wouldn't bother with chombo tbh unless you want to make all the changes Klaus is suggesting.<br>

WARNING: The Flash Center does not support using FLASH with Chombo, and <br>
the "experimental" Grid implementation based on Chombo has not evolved for <br>
a number of years. So proceed at your own risk.<br>

I believe the specific problem here is that Grid_getBlkIndexLimits.F90 has <br>
changed at some point, and does now work any more with the files under <br>
GridMain/Chombo/wrapper/unit_tests/2 as they are.<br>
<br>
In particular, for some reason not to be elaborated here,<br>
Grid_getBlkIndexLimits has become its own little Fortran module.<br>
Essentially the lines<br>
<br>
module Grid_getBlkIndexLimits_mod<br>
contains<br>
<br>
and<br>
<br>
end module<br>
<br>
were added.<br>
<br>
IF that is the only change relevant (I haven't checked), then you should <br>
be able to make progress by just changing the way in which the code<br>
under GridMain/Chombo/wrapper/unit_tests/2 refers to the subroutine <br>
Grid_getBlkIndexLimits.<br>
<br>
A simple way to do this would consist of replacing the explicit interface <br>
declaration for Grid_getBlkIndexLimits in flash_interfaces.F90<br>
with a line (in an appropriated place):<br>
<br>
use Grid_getBlkIndexLimits_mod, ONLY: Grid_getBlkIndexLimits<br>
<br>
(Cf. the regular Grid/Grid_interface.F90, which does the same thing)<br>
<br>
You may need additional changes, such as for making the Makefile aware<br>
of the .mod file that may now need to be considered in the source <br>
dependencies.<br>
