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></div></div></div></blockquote><div><br></div></div><div>There is no FETI-DP in PETSc.
