Hi dear Foamers
I do not know how to add an energy equation to my solver (porousSimpleFoam).my flow is incompressible and I do not know how to write this equation in openfoam.something like this format: fvScalarMatrix TEqn ( fvm::ddt(T) +fvm::div(phi,T) fvm::laplacian(alpha,T) ); TEqn.solve(); I see programmer guide but I don't understand so much. rho(fluid)*Cp(fluid)[sigma dt/dt + Udt/dx]=k d2T/dx2 + q'" + (mu/K) u^2 Sigma = [porosity(rho*cp)f+(1porosity)*(rhoc)s]/(rho*cp)f q"' = (1 porosity) q'"s k= (porosity*kf) + (1 porosity)*ks please help me if you know about this best regards mohsen

You can add a TE eqn file to code. But first simplify the your eqn. Also to make you understand code fvm::ddt(T) +fvm::div(phi,T) fvm::laplacian(alpha,T) this means dT/dt + UdT/dx]=k d2T/dx2 also since you are adding new variables like sigma, porosity etc...you need to first define them in the code. So, add TE eqn to code, define all new variables and include TE eqn it in main code file.... I think this will do.....
