Hello, 

I have a question concerning the setting-up of a structural transient dynamic FEA analysis of an elastomer cylindrical sample.

I have tried to set up the analysis according to the physical test that I want to replicate.

   It is about a radial compression test; I have defined Properties  Geometry, Model.

   In Analysis settings and the Number of steps, based on the dynamic experiment, Displacement is applied every 0.1 sec. We have, let`s    say 108 s in total to be the time of the test, and the measurements are 1000. However, when I input the number 1000 in Number of Steps,    a question mark appeared in the Analysis Settings of the Project tree on the left side, which means that it consider this wrong and the    study cannot run, appearing red icons on the left of the Inputs I have selected for the Solution.

   When I input the the Number of Steps to equal to 1, the simulation works correctly and I can have the results of the analysis I have set    (image 1). But my test is dynamic and the time step 1 does not indicates this in modelling.

I have tested different values for the Number of Steps, but it does not accept other than 1 in this case to run the analysis.

Could you assume why this is happening? Thank you.

Kind regards, 

FX

You can use 1 step with 1000 substeps.

You can't use 1000 steps, that is too many.
