I see. So you would have a 2-dimensional domain (x-z) but a 3-component problem (x-z-phi displacements)? In that case, deal.II would give you a 3x2 matrix for the gradients, which you will have to extend to a 3x3 matrix. You'll probably want to compute dot products of gradients in some simple way, so you should transform the 3x3 matrix into cartesian coordinates rather than leaving them in cylindrical coordinates. Does that help? I'm not quite sure any more what the exact question was ;-) Cheers W. ------------------------------------------------------------------------- Wolfgang Bangerth email: [email protected] www: http://www.math.tamu.edu/~bangerth/ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
