I am relatively new at using FEM software, and I have doubts regarding how to set the contacts between two solids that are joint by bolts. Here you can see the model (v7.1):
I have done it by myself but not sure it is correct.
Is it valid to create one contact constraint for all individual bolts (as I did, one for bolt-cylinder and other for bolt-frame) or I need to create an individual constraint for each one
Also do I need to split the exterior surface of the bolt so I can select only the side which is implicated in each contact?
About the mesh, is it over-meshed? I wonder If a coarser mesh would be enough
Can you please check the whole model to find incoherences? (for example, it seems weird to me the way the supports are set up, as I need to specify the point by coordinates)
Thank you for the help
