Hi Everyone,
I am trying to simulate a simple MBB problem (with filleted corners) using the Solid Mechanics interface. I am playing around with the Geometry Shape Order option, I am trying to make sure I get isoparamteric elements, given that the mesh discretization is quadratic with triangular elements. But so far the Geometry Shape Order keeps changing on its own depending on the mesh density. For instance, at coarse meshes, the Geometry Shape Order jumps to cubic. For a very fine mesh, the Geometry Shape Order jumps down to linear! How can I make sure I get isoparametric elements? Is there another way to fix the Geometry Shape Order?
Additional Important Info: 1. I figure out the Geometry Shape Order by extracting a numerical result at lagrange points using the LiveLink to Matlab, and it gives the coordinates of the points. 2. I know the 'sorder' can also be manipulated according the frame used, I checked that as well through the LiveLink to Matlab and it is kept at 2.
Any help is greatly appreciated.
Sincerely, Mohamed Abdelhamid
