Transient simulation


Tell me please, how to make a transient analysis of structural vibration?

I need a deformation of construction during 1 second.

And I have pressure from External loads, I have done a Modal analysis, and the lowest frequency is a 200 Hz.

Then I try to do a simulation, it takes a very long time.

    Transient simulations do take a long time. There are ways to speed them up if the model is linear. That means that the deflections are small and the materials are all linear.

    Do some research into Modal Superposition Transient Structural analysis (MSUP).

    Please describe in detail the time history of the Nodal Pressure load.
