Hello, everyone! I’m a new learner of FreeFEM, and I need to solve a reaction-diffusion system, which has two variables, just like the following form:

u_t=D11*(△u)+D12*(△v)+f(u,v),

v_t=D21*(△u)+D22*(△v)+g(u,v),

the △ denotes Laplacian, and the omega is 3D space.

I have watched some tutorial videos, but I haven’t seen similar examples. So, I really want to know if it can slove this kind PDEs, thank you so much!!!
