What happens with quadratic Hierarchic elements? I find it hard to imagine that we've got a bug in any of the 1D Lagrange shape functions, but if that's the case then using a different implementation (and a slightly different basis) for the same function space would be the fastest way to confirm it. --- Roy ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
