Looking initially it doesnt seem like you would get too much bending moment in the bolts themselfes.

One way that i found it to simplify things when it would be the same with a symmetry boundary is:
Imagine putting a piece of paper in the middle of your problem. Would the paper move from what is happening? If not then you have a symmetry boundary. Opposing equal forces is probably as...
Usually for clusters Linux is used, but that's probably not because simulations run much faster but because the terminal type input eases multiple user interactions with the machines.
To answer your question, the OS should not have any effect on the simulation times unless there are background...
Linear buckling analysis is made from eigenproblem analysis from the stiffness without imperfection, you will have different buckling loads for different stiffnesses and geometries. If you get imperfections from first buckling analysis you will get new buckling loads.
Maybe you are thinking...
Heat Energy = Degrees above reference temperature x Mass x Specific heat capacity
For 1kg of water 1 degree above reference temperature is equivalent to 4185.5 Joule.
E_h = T_r x m x c_p
Good luck
General-purpose polystyrene is clear, hard, and rather brittle according to wikipedia.
So that fits what it looks like at least (for example cd case fronts is made of this and they are very clear)
Generally for bending and such you need a couple of solid elements through the thickness to get a result that is close to what you can achieve with shell elements.
Is there some sort of thickness added to the surface of the solid elements that causes penetrations?
Also, if i am not mistaken SOL101 is a linear solver and this problem looks like it could be non-linear.
Good luck
