cute is on a distinguished road
Dear Foamer,

I am new in OpenFoam and would like to learn. I need your help.

Consider the following two PDEs that I would like to solve in a coupled manner.

ddt(C) = laplacian(d, C) - alpha*F(C)*X
ddt(X) = laplacian(DX, X) + F(C)*X - beta*X

where F(C) = C/(0.5+C), DX = gamma*sqr(X) and d, alpha and beta are some real numbers.

Could you please help me writing code for above system or provide some code snippet?

Thanks.
