I am trying to run a dynamic crash analysis in hypermesh, there are no errors in the model. But the solver ends in 1 second and only one result file is generated which doesn't contain anything.

Card info:

TStop:  0.002

Tstart:  0

Tfreq : 2e-6

    Hi,

    There could be several reasons for the engine crash. Please check the contacts in the model for any penetrations or intersections.

    Please share the starter out (_0000.out) and engine file (_0001.rad) files. Also what unit system are you following for this model?.

    There are no Penetrations in the contacts. The model is in MMGS.

    Hi,

    This issue is because of the unit consistency in the model. I changed the unit consistency to Tonnes,mm, seconds and it's running fine. The normal unit consistency followed with example values is attached along for your reference.

    The model file is also attached for your reference.

    Hi, I am trying to run a linear static analysis. But the solver won't even start. it says 'missing .rst file'.
