3D simulation optistruct

Max_21154

Dear all,

i´m trying to run a simulation with optistruct. I´m quite new to Hyperworks and usind the student version. I created a 3D model. The model should be fixed perpendicular to the northern and western edges and at the bottom in z-direction. On the eastern and southern edges there should be a enforced displacement by a certain value. Furthermore, a gravitation should act on the entire model. 

I created local coordinatesystems, SPC constraints and the gravity.

If i run the simulation the results are not as I want them to be. It seems that gravity is acting much too strong and the model is fixed at all edges in z-direction. I checked all units and the constraints but i couldn´t find any mistakes.

Thanks for help!

Kind regards

you have probably imported the geometry in the wrong scale, as your model has a huge dimension.

I assume from your material properties and gravity aacceleration that it would be in SI units.

But your part has a huge dimension.

You should probably adjust the model scale.
