Hello FEniCS community, I have been implementing a finite element solver in FEniCS with great results thus far, but I have been facing a technical obstacle when using more complicated functions in the variational formulation. For example, I have defined the following smooth function in Python via …

[image] stefanpetrevski: Thanks so much for this! Just to clarify, you are no longer using def diffu® as a Python function Right. interp1d resturns a function so I just moved it out. But you can keep it local, as you were doing before, too. [image] stefanpetrevski: For some reason, I am …
