Hi FOAMers,
I would like to solve this equation : laplacian(U) + U = (known field) where u is unknown volVectorField and should be solve implicitly. i don't know what i can do with the term (U), because to solve the equation implicitly i can write: Code:
solve ( fvm::laplacian(U) + fvm::U == knownTerm...) Does anybody know how i can deal with the U term to solve it implicitly? Tnx, |

Have you tried with:
fvm::Sp(1,U) ? (term I have written for example) #shakil |
