Hi everyone,
i tried to implement shock absorber in a shock analysis in optistruct.
I use tutorial in order to set non linear tranisient analysis.
I implement with table1d and pbusht the curve ForceVSdisplacement and applying a force i have checked if the the curves is right.
Then i have to checked if my model with this non linear springs has a right answer to established input.
In this case the model is loaded with an initial displacement and a gravity.
Finally i hate to load model with a curves VelocityVSTime.
Now i'm stopped at check problem.
My doubt are:
- the initial dislacement is inserted with IC and TIC in model but in the result there isn't initial dipslacement. Why?
- The tstep is calculated by solver? Is possible have a fixed timestep?
- maybe more simple simulate this problem with a explicit solver as Radioss?
Thank you for the answeres
