Hi All,

I would like to solve the following coupled equations using direct solvers. Kindly let me know how exactly should I go about doing 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)

where k1,k2,k3,k4 and k5 are some constant values.. f(C1) and f(C2) means the equation is a function of C1 and C2.

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
