136 * Revision 1.1.1.1.2.2 2005/03/15 07:23:55 gross
137 * Finley's interface to the SCSL library can deal with systems of PDEs now. tests shows that the SCSL library cannot deal with problems with more then 200000 unknowns. problem has been reported to SGI.
138 *
139 * Revision 1.1.1.1.2.1 2004/11/12 06:58:19 gross
140 * a lot of changes to get the linearPDE class running: most important change is that there is no matrix format exposed to the user anymore. the format is chosen by the Domain according to the solver and symmetry
