Control solver calculation time steps? [SOLVED]

Hello,

 

For the given boundary conditions and material model, RADIOSS solves the F=KD matrix at certain time intervals and considers the displacements from previous step for current step.

But how do I control these time steps? I want to have custom time steps and not a constant frequency.

I want only 1 step for the linear region, and varying steps for the non linear region.

Ideally I would like to enter the time steps in a list or tabulated form.

I can do this in Creo Simulate, but cannot find in HyperMesh.

Please guide me how to do this in HyperMesh RADIOSS(block120) profile?
