Hi all,
In createFields.h file under rhoCentralFOAM the following are the initial lines: Info<< "Reading thermophysical properties\n" << endl; autoPtr<basicPsiThermo> pThermo ( basicPsiThermo::New(mesh) ); basicPsiThermo& thermo = pThermo(); volScalarField& p = thermo.p(); volScalarField& e = thermo.e(); const volScalarField& T = thermo.T(); const volScalarField& psi = thermo.psi(); const volScalarField& mu = thermo.mu(); Can anyone please explain some terms like thermo. Also, I want to define gamma = Cp/Cv. I am not able to figure this how to do. I used the following const volScalarField& gamma = thermo.Cp() / thermo.Cv(); Info<<"GAMMA= "<< gamma <<"\n" <<endl; But it fails saying hanging pointer while executing the Info line. a part of logfile: 1.4 1.4 1.4 1.4 1.4 1.4 1.4 1.4 1.4 1.4 1.4 1.4 1.4 ) ; boundaryField { --> FOAM FATAL ERROR: hanging pointer, cannot dereference From function PtrList: ![]() in file /home/Ashwani/OpenFOAM/OpenFOAM-2.1.1/src/OpenFOAM/lnInclude/PtrListI.H at line 134.
