I faced error messages below when I was to solve a simple case with chtMultiRegionSimpleFoam.
Please help me - where do I start to find the reason for this error message?

*** Reading fluid mesh thermophysical properties for region hecavity

Greetings Joshua and welcome to the forum!

Not much information you're giving us. All that can be seen from this is that:

• There has been a SIGFPE: http://en.wikipedia.org/wiki/SIGFPE#SIGFPE
• It happened when running the method "calculate()" for the chosen thermodynamic equation.

This implies that something is improperly defined, such as temperature set at 0 Kelvin, or pressure defined at 0 Pa... or something else.

Best regards,
Bruno

It was a problem of unrealistic boundary condition generated in the 0 directory.

Actually a zero kelvin problem.

Thank you for your great answer Bruno.
