I've found something that looks like somewhat outdated code (e.g., it uses SLESxxx) for FETI-DP:<br>src/mat/impls/feti<br><br>It appears that this matrix class actually implements a FETI-DP based preconditioner.<br>Is that right?<br>
Perhaps some (or all) of it can be rolled into a more general PCFieldSplit-type framework?<br>Any ideas?<br><br>Thanks.<br>Dmitry.<br>
