Hi Mostafa,
Thanks for the info. My first doubt is the unit consistency issue. Please first check whether the input value for the velocity is consistent with the unit system you used in the model.
If the units are consistent, please verify again whether your input velocity-time curve reproduces the same displacement curve input in your other model.
My next doubt is related to manual time scaling in the simulation (i.e. scaling the time down by a factor and correspondingly scaling up or down other time-dependent variables in the simulation like velocity and strain rate). In case you used a time scaling appraoch, please check you properly scaled parameters.
Please keep me posted.
Thanks,
Pedram
