A problem in rhoCentralFoam
 
this error becomes appear after rhoCentralFoam run.what means "e" in this error?if it means epsilon I have set to laminar at this stage of problem.
thanks for helping!

Hey, i have the same problem! Did you find what to do?

regards

hi
type h instead of e in thermophysical file to use of enthalpy instead of internal energy
let me know if it solved or any problem occured.

It works just fine,thanks.

By the way, do you know if rhoCentralFoam has any problems with low Mach numbers ?
I solved an incompressible case with icoFoam and now i'm trying to get the same results with the compressible solver,as long as my flow remains incompressible.

Regards again

I'm glad it resolved.
I don't think rhoCentralFoam has any trouble with low Re problems.
don't have to feel any doubt about this change!
anyway I'll be happy if i can help any problems.
