Hi everyone, I would like to speed up my code and I have the following problem: I want to create a more complicated Expression based on a finite element function. I can create the functionality I need with an UserExpression, which looks like this: class profile(fenics.UserExpression): def __init__…

The following modified version appears to work: from dolfin import * import numpy as np cpp_code = """ #include <pybind11/pybind11.h> #include <pybind11/eigen.h> namespace py = pybind11; #include <dolfin/function/Expression.h> #include <dolfin/function/Function.h> class Profile : public dolfin:…
