Hello,
I have an assembly that has somewhere a hole with a round bar that exactly fits in this hole.
But when meshing the assembly, the mesh of the hole and the mesh of the bar are different.
The result is that the different parts do only seem to touch each other at the edges of the mesh,
resulting in high stresses. See picture.
I tried to made a dirived part from the assembly, but that one does not finish meshing. After 48 hours
the progress bar is still half way. While the one above did finish in about 15 minutes.
What can I do to make the meshes match?
Hi Melomania,
<<What can I do to make the meshes match?>>
Inventor Stress Analysis doesn't need conforming mesh nodes to transfer loads. We use contact-based technology.
<<The result is that the different parts do only seem to touch each other at the edges of the mesh, resulting in high stresses>>
As you've found the meshed model's geometry is not exactly the 'true' model geometry in some cases. The way to not have polygonal cylindrical faces is to:
1) Check the Mesh Settings option "Create Curved Mesh Elements"
2) You've already found the "Maximum Turn Angle" setting in the Mesh Settings, which will increase the number of elements for curved faces
3) Local mesh control to have a tighter mesh near areas of interest. It will yield better results than a global setting to increase the mesh density.
I've attached two images showing before and after option 1)

Hope this helps...please let us know if you have additional questions or comments.
