- - **Can Poissonbs equation be solved in FOAM like this**

For transient problem, we can For transient problem, we can achieve the solution as following:
fvVectorMatrix UEqn ( fvm::ddt(U) + fvm::div(phi, U) - fvm::laplacian(nu, U) ); solve(UEqn == -fvc::grad(p)); Then, if I want to solve a arbitrary Poisson's equation or elliptic equation in my solver code, I can do it with the similar code lines shown above? Thanks. BTW, I have successfully include VTK libs in my OpenFOAM solver. Thanks. |
