Hi there, I am trying to model reaction-diffusion of biological cell signals, with the cells acting as point sources as they secrete the compound. The code below runs but my approximation at point sources (supply term) is very clumsy. I have looked into posts such as PointSource in dolfinx - dolfi…

Upgrade to 0.7.2 or 0.7.3. They have critical bugfixes in that determine_point_ownership, see Release v0.7.2 · FEniCS/dolfinx · GitHub

Looked at this as well Point Sources (Redux) ?
