KNOWN ISSUE: Use of zero pressure polynomial for specific heat in Particle User Fortran (Class 3 Error)
If the specific heat of a particle transport phase is set using a zero pressure polynomial, and this specific heat is subsequently used in a Particle User Routine, then the software will use an incorrect specific heat for the particles in the routine. The value used is either 1.0, or the value at the lower temperature limit if set, so the value could be vastly in error.
This is due to a coding error.
No workaround is currently available.
