Last change on this file since 5772 was 5772, checked in by Eric.Larour, 15 years ago

New solution strategy, based on creation of Kff, Kfs directly,
instead of Kgg. Idem for pf instead of pg.
Kept backwards compatibility for now, and only applied to macayeal diagnostic
in 2d. Will switch to this new strategy in the near future.

4 * This object will hold the element matrix on the g-set, the internal as well as external
5 * dof lists in the f and s sets.
