Verification & Validation

One way to check the accuracy of the simulation is to refine the mesh and re-run the simulation. The smaller the element in the mesh, the more accurate the simulation will be. The only drawback is longer computation time. To refine the mesh, insert Body Sizing on the specimen and set the element size to 0.003m. Also, enter 0.003m for the element size in the Details of "Mesh". This will ensure both the shell and the specimen are meshed with 0.003m elements. The original mesh has 620 Elements and 4533 Nodes and the new mesh has 894 Elements and 6152 Nodes.
