Hi All
I would like to solve coupled transport equations (not using relaxation technique). Can someone help me which tutorial I should go about looking to solve my problem. These are my equations ddt(C1) = - K1 * laplcian(C1) - K2 * laplacian (phi) ddt(C2) = - K1 * laplcian(C2) - K2 * laplacian (phi) K3 * laplacian (phi) = K4 where k1,k2,k3,k4 are some constant values.. Kindly help me out. I tried searching in the forum and could not get any information pertaining to this. I don't think I can use conjugate heat transfer solver for this. Vishal |
Look at scalarTransportFoam in
Look at scalarTransportFoam in the '$FOAM_SOLVERS/basic' folder

What about solving your equati
What about solving your equations in a segregated manner?
First solve: K3 * laplacian (phi) = K4 and then: ddt(C1) = - K1 * laplcian(C1) - K2 * laplacian (phi) ddt(C2) = - K1 * laplcian(C2) - K2 * laplacian (phi) or is there any coupling in C1 and C2? Best regards Christian |
Hi Christian and Prashanth,
Hi Christian and Prashanth,
Thanks a lot for the reply. I just missed one term in my equation. The equations look like this, ddt(C1) = K1 * laplcian(C1) + K2 * laplacian (phi) ddt(C2) = K1 * laplcian(C2) + K2 * laplacian (phi) K3 * laplacian (phi) = K4 * f(C1) + K5 * f(C2) (Further this is a stiff equation) where k1,k2,k3,k4 and k5 are some constant values.. I want to solve them directly and not using relaxation procedure. Kindly offer some suggestions as to how to go about solving them. May I know which tutorial i have to follow. Thanking You Vishal |
