So perhaps it is better to use a composite preconditioner, calling PCCreate(comm,&pc) and next PCSetType(pc, PCCOMPOSITE), and finally add your preconditioner followed by the smoother... I think your original approach was wrong, if you look at GMREScycle(), you will see that this routine applies the PC inside each cycle. -- Lisandro Dalc?n --------------- Centro Internacional de M?todos Computacionales en Ingenier?a (CIMEC) Instituto de Desarrollo Tecnol?gico para la Industria Qu?mica (INTEC) Consejo Nacional de Investigaciones Cient?ficas y T?cnicas (CONICET) PTLC - G?emes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594
