Hi there,

I was wondering how to get the density-field if using some compressible solver?

Beside rhoCentralFoam I think all other solvers define rho as a NOWRITE-object (like basicThermo does with psi, too). As density and compressiblity are a fundamental thing of compressible flow - if not it would be incompressible, right? - there should be a way to visualize those fields in postprocessing, shouldn't it?

Or do I have to calculate the Mach-Number, out of that the compressiblity, and according to this finally the density? Sounds complicated to me..

Is it advisable as an easy solution to create a new solver as a copy of the existing one, say sonicFoam, with rho defined as AUTOWRITE-object?
