Hi Maria, There are many possible causes for a con2prim failure, but generally if unphysical conservatives are input then failures are inevitable. The information provided doesn't tell us much. I've always included a super verbose error output when a failure occurs within my own con2prim implementations, so that I can backtrace any problems. It would be useful to see if this feature either exists (and can be enabled with a parameter file setting) or could be added.
