» What does the error in COSMOSWorks "Mesh and Model volumes are
» significantly different" mean and how do I correct it?
Hello jfcook,
We located some information regarding your question. It's from Greg Sivik on the SolidWorks discussion board. Greg writes:
Likely there is a quality check comparing the solid and the elemental volumes. A significant deviation means the mesh doesn't represent the geometry well. Generally, try a denser mesh. If there are areas you can see where the mesh doesn't represent geometry, try denser local mesh control.

Tets need to be close to a pyramid shape. Flattened Tets, have a poor aspect ratio (height/base) and will cause this error. Twisted Tets will also cause this error. Reducing the tet size can help. I would suggest mesh control in tight areas and prevent a huge solution matrix.
If your analyzing thin objects, you may want to try shell elements.
