Dear Rashiga,

3) In my archive, the remote point is scoped to a vertex and not a node, so it is persistent after remeshing.

1) The way bolt pretension works is that it splits the body in half and grabs the two new faces created and pulls them together with the force that was specified. In the image below, you can see the Y-deformation of the Bolt Pretension, which creates the appropriate tension forces in the top and bottom parts of the shaft.

 

2) Controlling where the program splits the body to apply the Bolt Pretension is the reason to split the shaft into 3 pieces.

Best regards,

Peter
