Thanks for your prompt reply! Adding parameters as variables is a good idea. I will try that first. For now, I have already had my serial version code working using MeshData format .xta. I am wondering if you can give some hints on how to load that data in a parallel setting.
What I am thinking is to load it on the first processor and distribute to other processors. (1) How should I achieve this? (2) Should I use add_vector instead of add_variable() to avoid increasing the number of dofs. Right?
