Why the critical timestep for the same spheres and clumps are not same?

Asked by nie jiayan

Hi, all. Now I conduct an contrast simulation about the triaxial element test for spheres and same clumps, which means that the clump is generated by the former single sphere. All the model parameters for both simulation are the same like geometry and physical parameters including sphere position, and young and density, radius and so on. However, I find it is amazing that it is different for the critical timestep of both specimen determined by Utils.PWaveTimeStep. Why is it?

Hello,
looking to the source code, I see no reason.
Please provide a MWE (minimal working example) [1].
thanks
