ePsiThermo<pureMixture<constTransport error
 
could someone explain about this error in 2.1.1 version?

Hi Ehsan,

It's a floating point error ("sigFpe"), which either means a division by zero or infinite or something similar. For some more information: http://en.wikipedia.org/wiki/SIGFPE#SIGFPE

Said error occurred at:
Code:

#3  Foam::ePsiThermo<Foam::pureMixture<Foam::constTransport<Foam::specieThermo<Foam::hConstThermo<Foam::perfectGas> > > > >::calculate()
Without seeing the real numbers on the file you are using, it's (nearly) impossible to guess which value is invalid...

Best regards,
Bruno
