I am in trouble when testing the method that solving the PDE problem by Comsol.
A very simple problem that: du/dx=2*x is be solved with the boundary condition of u=1 when x=1. It is very strange that the result is oscillating. what wrong with it?
The mph file is in the attachment.
Thank you very much!
