Hi FOAMers
I change this part of icoFoam code: fvVectorMatrix UEqn ( fvm::ddt(U) + fvm::div(phi, U) - fvm::laplacian(nu, U) ); solve(UEqn == -fvc::grad(p)); to: fvVectorMatrix UEqn ( fvm::ddt(U) + fvm::div(phi, U) - fvm::laplacian(nu, U) + fvc::grad(p) ); solve(UEqn); but in the second case I got divergence. Can any one tell me what is the problem? Best regards |
