Surface Model Mesh Challenges

The stresses in this leg are wrong:
The stress distribution in the leg to skirt attachment is uneven. Turning on the mesh shows the uneven mesh that is supposed to be connecting these two parts.
The problem does not go away with mesh refinement or tolerance adjustments. The problem is intermittent – some parts will join, some not. A recent update to SolidWorks Simulation can fix this problem:
Curvature based meshing was not included in SolidWorks Simulation 2008. This example was run in SolidWorks Simulation 2010.
Here the standard mesher was used with the leg surface knit to the skirt. The standard mesher produces a better looking mesh.
