First, one divides the space around the solid structure into small pieces. Then one solves systems of equations for all of those pieces. Sounds like a good job for objects to me.
If it is not such a good idea, why are those pesky norwegians using OO for finite element analyses? Received on Fri Jul 07 2006 - 00:24:13 CEST
