FreeFem user-defined function
Yeah, I got the type wrong. This is possible, but the function needs to be evaluated over an object of the same type. For example,
mesh Th=buildmesh(...);
fespace Vh(Th,P1);

FreeFem user-defined function [closed]
I'm trying to solve the steady-state heat equation with a space-dependent thermal diffusivity in FreeFem. I.e. $$\nabla\cdot(\kappa(x,y)\nabla T) = 0$$
I'm hoping to read in from a file locations $(x_ …
