Can it solve the coupled PDEs in 3D?

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:


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!!!

yes not problem ,
first try in 2d more simple,
and choose the time stepping schema.

remark, the numeric depend strongly of the 2 function f and g.

Thank you very much for your suggestions!!! I will try!
