Hi, I am already using PETSc to solve my momentum and poisson equations. However in some parts of my code, I need to solve a dense (usually) or sparse matrix, which arises from the radial basis function interpolation. Depending on the problem, it can be a big or small matrix.
I am thinking whether to use PETSc or just a simple solver. Can you recommend the minimum size of sparse or dense matrix to use PETSc? Thank you. -- Yours sincerely, TAY wee-beng
