    What can we get from modal analysis beside natural frequencies and corresponding shapes ?

    My question is : Can we get a hint about overall structural behaviour of a system from modal analysis ? Such as: even under a static case the system will try to deform like its mode shapes. Is this statement true ? I am trying to understand what can I get from modal analysis so I can use these...

    When do ABAQUS recognize contacts ?

    Hello, Let us say I have a model of a ball and a square plate. I throw the ball towards the plate and let us say there is 10 mm gap between them. When will ABAQUS recognize the contact between them, is there a specific number like for example: when their distance become 1 mm or something ...

    A question about Kinematic (RBE2) and Distributing (RBE3) couplings

    yes exactly, I mean boundary condition, pin, encastre or whatever.

    A question about Kinematic (RBE2) and Distributing (RBE3) couplings

    Hello, As the title says I have a question about couplings which can be something very fundamental yet it is puzzling me. Let's assume that we have a classic MPC with one reference point and on this reference point we are applying a constrain. When we try to solve this problem in a static case...
