refinement while PLANE42 converges at a slower rate. The percent error in energy norm results indicate
that global accuracy is best obtained by PLANE82 for any given DOF set. However, the σy stress at target
point 1 shows that for uniform refinement, PLANE42 gives better results (at that point) under moderate
mesh refinement. A fine mesh using PLANE42 in place of a coarse mesh of PLANE2 or PLANE82 may
produce better localized stress values. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 2–11 VMC3: Barrel Vault Roof Under Self Weight
