57 * $Log$
58 * Revision 1.8 2005/08/12 01:45:43 jgs
59 * erge of development branch dev-02 back to main trunk on 2005-08-12
60 *
61 * Revision 1.7.2.1 2005/08/04 22:41:11 gross
62 * some extra routines for finley that might speed-up RHS assembling in some cases (not actived right now)
63 *
64 * Revision 1.7 2005/07/08 04:07:59 jgs
65 * Merge of development branch back to main trunk on 2005-07-08
66 *
67 * Revision 1.1.1.1.2.4 2005/06/29 02:34:57 gross
68 * some changes towards 64 integers in finley
69 *
70 * Revision 1.1.1.1.2.3 2005/03/02 23:35:06 gross
71 * reimplementation of the ILU in Finley. block size>1 still needs some testing
72 *
73 * Revision 1.1.1.1.2.2 2005/02/18 02:27:31 gross
74 * two function that will be used for a reimplementation of the ILU preconditioner
75 *
76 * Revision 1.1.1.1.2.1 2004/11/12 06:58:19 gross
77 * 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
78 *
79 * Revision 1.1.1.1 2004/10/26 06:53:57 jgs
80 * initial import of project esys2
81 *
82 * Revision 1.3 2004/08/26 12:03:52 gross
83 * Some other bug in Finley_Assemble_gradient fixed.
84 *
85 * Revision 1.2 2004/07/02 04:21:13 gross
86 * Finley C code has been included
87 *
88 * Revision 1.1.1.1 2004/06/24 04:00:40 johng
