i am simulating (static structural) a three point bending test with two fixed supporting cylinders and one load cylinder in the middle (displacement). I wanted to see if a changing velocity of the load cyl. creates different results for force reaction etc. I already increased the number of steps but is it possible to increase the time of one load step? The displacement is linear i just want it to be slower.
thanks for any ideas

Static Structural analysis solves the equations of static equilibrium. It is not going to give different results when you change the number of steps. That does not change the velocity of the cylinders. You are describing a dynamic effect. There is an analysis system called Transient Dynamics that solves the equations of dynamics. In that analysis you can alter the velocity of the load cylinder and look for an effect on the results.
Something different from the above description is rate-dependent material properties. The idea that a material is stiffer if the deformation is applied at a high velocity. Is that what you are trying to simulate?

Thank you Peter!
The transient dynamics was what i looked for!
