Hi, I'm working with step-17 and I would like to extend it to fit to my simulation. The requirement is that the solver must be called over the same system matrix a big number of times. Only the RHS is changing, so I would like to have the solver_control, solver cg and preconditioner as members of the class, instead of creating them every iteration as in the example.
However, making any of these 3 objects a member of the class an constructing it in the initialization list of the class, gives different errors. I think this is a problem related with the Petsc solvers because I could do it with the normal iterative solvers without Petsc. Is there a way to avoid creating these 3 objects every time? Is it even worth it, or these objects are very light? Please take into account I must repeat it these step ~50,000 per simulation. Thank you very much.
