I'm new with NX Nastran and I need to figure out which Nastran solution should be used to simulate forced vibration on a structure that include non linear contact.
My boss asked me to analyze the potential solutions in odder to purchase the needed license. so far I think the only choice is the 701 dynamic explicit solution, any other suggestion on how to simulate this problem?
thank you very much.
your conclusion about SOL701 is correct. Here my thoughts:
SOL701 has an explicit time integration scheme using very small time steps by default. This makes it suitable for high speed effects. Nonlinearity like contact does not add complexity to the simulation since we do not work with iterations when solving the problem.

Thank you verry much , this was really helpfull. The only problem now is that i can't find any reference or guide on how to set the explicit model, should you know any refferences or tutorials please let me now.
