[petsc-users] Loading Laplacian as Module

Fri Sep 23 13:09:53 CDT 2016

Thanks Barry, for the quick reply,

I tried doing that once recently, not for this problem though, but it looks
like the model i'm working on isn't optimized at all for memory leaks, and
valgrind stopped with thousands of errors before reaching this part of the
execution.

Is there maybe an alternative approach ? or it would be better to just get
the model in better shape already ?

Thanks
