@mwestphal can you elaborate just a bit more? I am fairly new to Paraview. I wish to plot over the 1D spatial domain, the numerical solution in red, the analytical solution in blue, and have them both evolve as I click the time-animation control buttons. Ideally, the numerical and analytical curves should lie on top of each other.
Why a filter? I don’t want to filter any existing data. I think you meant a ‘source’, right? However, the python calculator source is greyed out.
