1.May I know which parameter can control the index of cells and add the local
stiffness matrix of cell into global matrix?
Lance,
I think you probably want to go back to the programs cook_membrane.cc builds
on. Every tutorial program in deal.II, starting with step-3, has to add local
contributions to the global matrix. Please read through step-3, for example.
