Abstract
We consider elliptic problems with discontinuous coefficients discretized by finite elements on non-matching triangulations across the interface using the mortar technique. The resulting discrete problem is solved by a FETI–DP method using a preconditioner with a special scaling described in a forthcoming paper by Dokeva, Dryja and Proskurowski. Experiments performed on up to a thousand processors show that this FETI–DP mortar method exhibits good parallel scalability.
