I am trying to simulate a model with two components bolted together. How do I establish physical boundaries between the two parts so that they do not overlap during simulation? Do I utilize surface to surface contact?
Note I am fairly new to NX and I have limited FEA experience. Any help would be great. Thanks.
Can you clarify connected meshes? My part has bodies with surfaces that are in contact during initial assembly and other surfaces that come in contact during simulation. I want to prevent the bodies from intersecting during simulation. I can establish the face-to-face contact for the surfaces that are in contact during the initial assembly but I am having issues with the surfaces that intersect during simulation. Thanks for your help.
The meshes of the contact pairs must not share the same nodes.
If you have two faces that have a gap in between at the start of the
simulation and are colliding during simulation, you have to take care that
the value of the maximum searching distance of the contact is greater than
the existing gap at the beginning of the simulation. You can change the searching distance in the Face Contact Edit Menu (right-click on Face Contact).
Probably the term searching distance is sligthly different in your menu
because my language setting in Advanced Simulation is german.
