Revision 4143 - (view) (annotate) - [select for diffs]
Modified Thu Jan 17 08:48:47 2013 UTC (6 years, 9 months ago) by gross
File length: 21249 byte(s)
Diff to previous 4132
documentation of minimizer update plus clarification of notations on the code

changes to the boundary conditions.

Revision 4120 - (view) (annotate) - [select for diffs]
Modified Tue Dec 18 04:49:37 2012 UTC (6 years, 10 months ago) by gross
File length: 20204 byte(s)
Diff to previous 4102
some improvements to the robutness of the minimizer:
  a break down in the orthogonalization is hnadles via a restart.
  a restart can now be set manually
  the iteration throughs now an exception in case of failure.

It is also possible to set the density anomaly to zero for regions below a certain depth. 





Revision 4102 - (view) (annotate) - [select for diffs]

more improvements on rescaling of weights. We now try to balance the gradients rather than the values.

Modified Tue Dec 11 06:55:20 2012 UTC (6 years, 10 months ago) by gross
File length: 18353 byte(s)
Diff to previous 4097
minimizer uses now a relative change to solution to terminate iteration. Gravity still has problems
