Dear Foamers,
we are currently struggling with the total pressure inlet BC (totalPressure). We do not fully understand the meaning of some of the require parameters in the "p"-File: Code:
/* PRESSURE INLET */ patchname_pressureinlet { type totalPressure; p0 uniform 1.e5; /* Total pressure p0 = p + 1/2*rho*U^2 */ U U; phi phi; rho rho;/none; psi psi;/none; gamma 1; } Code:
FatalErrorIn ( "totalPressureFvPatchScalarField::updateCoeffs()" ) << " rho or psi set inconsitently, rho = " << rhoName_ << ", psi = " << psiName_ << '.' << nl << " Set either rho or psi or neither depending on the " "definition of total pressure." << nl << " Set the unused variables to 'none'." << "\n on patch " << this->patch().name() << " of field " << this->dimensionedInternalField().name() << " in file " << this->dimensionedInternalField().objectPath() << exit(FatalError);

Dear Bastil
Did you find answers to your question ? I also have the same question and have not received any reply yet. Please let me know if you have figured out ? Thanks Vaidya |

And it is also depending on incompressible or compressible simulation. Either you have a field for compressible simulations or just the value in the transport properties. If you don't add them they will be calculated automatically. And I also guess that psi is about particle movement depending on the velocity (streamfunction) and directly depending on rho so if you fix one of them the other will be calculated! But may I'm wrong Last edited by klio; April 17, 2012 at 03:25. |

Hello,
I know this is an old thread but I was looking around for the same answer and I found in which header file OpenFoam describes these variables: http://foam.sourceforge.net/docs/cpp/a04465_source.html |
