Hi, I need to investigate the performance of FETI-DP on a heteregenous problem with a proposed preconditioner/scaling and different parameters. I do not want to reinvent the known. I need to investigate the outcomes of my research on top of FETI-DP.
I have seen several papers in literature discuss about the FETI-DP implementations in PetSc. However, seems none of them is provided in public. I have come across several functions in PetSc with *FETIDP* names. But, since this algorithm is quite different then the ksp algorithms, I could not figure out how to use them. I have two concrete questions; 1- Is it possible to complete a FETI-DP solution with the provided functions in current PetSc release? 2- If so, what is the calling sequence for these functions? Thanks in advance, Alp
