Still there values are concentrated to certain points, should the CPRES be evenly distributed ---

Try linear finite elements. ---

Just switch Second order to No in Meshing parameters: ![meshing](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/b/b0dce5855e5731af69c06ed472a63c3bf426001e.jpeg) ---

You can also try Hexa elements. Mesh with quad dominated and extrusion. These are my settings and I obtained VM on the lip almost constant even with second order elements. ![screenshot.17](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/b/b3a54d389b3ce1191413a5fe79bf50b1161a7a2a.jpeg) ![screenshot.16](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/6/6cb5c2830bcc0b9f999fed7bd2f8f46125206350.jpeg) ![screenshot.15](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/5/5bd7fe6abbb7a52347c31fe9cd067f35a03fda36.jpeg) ---

Using Linear FE gives the same result, but trying now with Hexa elements. @ANYS if you create the mesh in Prepomax can you share the mesh settings ---

I mesh it outside but you can use both, extruded or revolve algorithms with Delaunay for quads inside Prepomax. ![screenshot.34](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/1/1810f2404fbb09a88e68c386200e3d70bd3bb017.jpeg) ![screenshot.33](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/a/a97ac3b8c490490059b13d1c71d890343b328e01.jpeg) ![screenshot.32](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/9/9b2d8f2222fbabc9182125df76a329c057919aa7.jpeg) ---

> [@Droid](#): > > shaft and a bush with interference fit with contact pair Calculix has problems with this kind of geometry where there is contact between two cylindrical parts. I get this a lot when I have pin to compute. To solve this problem I usually do what Gunnar suggested me in this post (i.e., I use the compound part) [Bolts shear contact not working correctly](https://prepomax.discourse.group/t/bolts-shear-contact-not-working-correctly/1734) (see his first post). I tried to write about the problem on the Calculix forum, but they suspended my account and deleted the post (I honestly don’t know why, I was neither insulting nor rude, I just rewrote what you see in the post I linked to you). I hope this solves your problem. ---

Thank you @ANYS this worked. [Previous page](https://prepomax.discourse.group/t/interference-fit-implementation/409.md?page=1)
