I am trying to model the Laplace equation using finite element edge with element basis functions. I have written code using node basis function to solve the problem. The results obtained using that method are good. I will be grateful if you can shed some light on how to solve the Laplace equation using the edge element basis function. I have referred to the paper written by I. Anjam and J. Valdman, "Fast MATLAB assembly of FEM matrices in 2D and 3D: Edge elements". Looking forward to other literature related to this problem. I am coding this problem in Python.
