Hi, I need to recompute the preconditioner every once in a while. So far I do this "manually", i.e. I destroy ksp and re-create and reset it whenever needed. I am wondering if there is a cleaner way of doing this via a PETSc function. I found KSPreset but there are no examples about it so I am not sure it is what I am looking for. Could you help please?
Thanks, Michele
