On p==1 elements our projection is just nodal interpolation and the evaluation will only use nodal data. Even p==2 Lagrange elements may produce data requests from non-nodal quadrature points, though. --- Roy ------------------------------------------------------------------------------ Get your SQL database under version control now!
