Hi Folks,
I have splitted the convection into different terms U*U = U*U + B*Udelta*U + B*U*Udelta + B*B*uDelta*uDelta where B is a volScalarField and uDelta a volVectorField. Both fields are calculated explicitly in a previous step. A possible discretization could be fvm::div(phi, U) + fvc::div( B*Udelta*U + B*U*Udelta + B*B*uDelta*uDelta) Is there a way to discretize the remaining terms also implicitly? (If I use fvm::div or fvm::Sp I'm getting an error reporting incompatible fields for operation) Best regards Matthias |
