Wrench2D Tutorial: Second order elements & inhomogeneous Dirichlet data
I made some minor changes to the wrench2D tutorial to have inhomogeneous Dirichlet data (prescribed non-zero displacement). It seems to work for linear elements but when activating the second order option/flag, the results near the Dirichlet boundary with inhomogeneous data are wrong. I attached the updated wrench2D.pro as well as screen shots of the results with linear / second order. Are further changes required to deal with inhomogeneous data? Or is there an issue with the elimination of essential boundary data when using higher order elements.!
