I keep on getting this error message and I'll change something (never the same thing twice) and then it will go away and pop up again a few minutes later.

#0 Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam171/lib/linuxGccDPOpt/libOpenFOAM.so"

Any thoughts would be much appreciated.

Line 1 in your stack trace says there is a floating point exception, so somewhere you are having a problem with the math trying to do something impossible (square root of a negative, divide by zero or infinity)

Line 3 in your stack trace says there is something wrong with a division operator somewhere in your solver. Change your timestep write to every iteration and see if there is a field that goes to zero when it shouldn't. I'm not familiar with that solver, so you'll need to check the code yourself and see where division of one field by another occurs.

I think it ended up being a purely dimensional issue. It seems like there was something about where the dimensional error was occurring (I was dividing) that caused the error. Regardless, all is resolved.

Thank you for your help.
