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.

Hello,
I have an error when simulating unequal mass binaries with PRThorns GRHydro for certain combinations of EOS and mass ratios.
Using the same parameter file for an equal mass binary case, seems to work with various EOSs, and for certain EOSs, even for unequal mass.
Any inkling of why this might happen? I tried with both ppm and weno recon_method, and with higher refinement. What do you think would help?
