67 * Revision 1.8 2005/08/12 01:45:43 jgs
68 * erge of development branch dev-02 back to main trunk on 2005-08-12
69 *
70 * Revision 1.7.2.2 2005/09/07 06:26:22 gross
71 * the solver from finley are put into the standalone package paso now
72 *
73 * Revision 1.7.2.1 2005/08/04 22:41:11 gross
74 * some extra routines for finley that might speed-up RHS assembling in some cases (not actived right now)
75 *
76 * Revision 1.7 2005/07/08 04:07:59 jgs
77 * Merge of development branch back to main trunk on 2005-07-08
78 *
79 * Revision 1.1.1.1.2.4 2005/06/29 02:34:57 gross
80 * some changes towards 64 integers in finley
81 *
82 * Revision 1.1.1.1.2.3 2005/03/02 23:35:06 gross
83 * reimplementation of the ILU in Finley. block size>1 still needs some testing
84 *
85 * Revision 1.1.1.1.2.2 2005/02/18 02:27:31 gross
86 * two function that will be used for a reimplementation of the ILU preconditioner
87 *
88 * Revision 1.1.1.1.2.1 2004/11/12 06:58:19 gross
89 * 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
90 *
91 * Revision 1.1.1.1 2004/10/26 06:53:57 jgs
92 * initial import of project esys2
93 *

95 * Some other bug in Finley_Assemble_gradient fixed.
96 *
97 * Revision 1.2 2004/07/02 04:21:13 gross
98 * Finley C code has been included
99 *
