Full K should never be constructed #7

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Even when compiled with -DCUSP switch, the code allocates memory for full K 
matrix. For 20-20-100 problem full K needs more than 100 GB of memory, which is 
of course unacceptable. Since for these large problems GE solver that works 
with full K is very slow, it is useless anyway. A sparse CPU solver should be 
used instead of the current GE and everything related to the full K matrix 
should be deleted from the code.

The current version of N-S solver does not allocate full K.
