SUMMARY
The discussion focuses on implementing Finite Element Methods (FEM) to solve a problem with a discontinuous exact solution. The exact solution is defined as u = x^5/20 - x/20 for x in the interval [0, 0.6) and u = sin(x) for x in (0.6, 1]. The user has successfully set up the matrices Au = f but is uncertain how to handle the discontinuity in the code. The problem emphasizes the need for a robust approach to manage discontinuities in FEM implementations.
