[petsc-users] KSP: when to use initial residual norm (ksp_converged_use_initial_residual_norm)

Hi, we are solving a time dependent problem with a single KSP in every time step. We are debating which convergence criterion to use. Is there general guidance around when to use one of the norms with initial residual (ksp_converged_use_initial_residual_norm or ksp_converged_use_min_initial_res
