<div dir="ltr"><div><div><div><div><div>Hi,<br><br></div>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.<br>
<br></div>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. <br>
<br>I have two concrete questions;<br><br></div>1- Is it possible to complete a FETI-DP solution with the provided functions in current PetSc release?<br><br>2- If so, what is the calling sequence for these functions?<br>
</div><br></div><div>Thanks in advance,<br><br></div><div>Alp<br></div></div>
