Hi all,

I'm looking at doing a FE diffusion simulation in SCIRun, and had
couple of quick questions:

1) The only FE code I've seen is in the BioPSE module for solving the
electric potential problem -- is anyone solving any other FE problems
using SCIRun?

No currently we only have a solver for the Poisson equation, and not for diffusion equations.

2) I've found two different versions of the BuildFEMatrix code -- one
in Core/Algorithms/Math and one in
Packages/BioPSE/Core/Algorithms/NumApproximation.  It looks like the
one in Core/Algorithms/Math is the one being used currently, is this

Yes, that is right the Packages/BioPSE/Core/Algorithms/ NumApproximation are on the list to be removed from the code.
The new code is currently in Core/Algorithms/Math



Any suggestions are appreciated.
