Convolution of TrialFunctions

Hello everyone,

I’ve been trying to figure out how to assemble the following system:

a(u, w) = \int_{\Omega} (hu)w dx
l(w) = \int_{\Omega}(g
h)w dx

for u and w trial and test functions in H1(\Omega) with order 1 polynomials. I saw a previous post, and managed to find the repository which I think solves my problem, but I’m having trouble contacting them because I have problems with how to build it. Having said that, has anyone used this functionality before, and if so, how did you managed to install it?

thanks in advance,
