How to calculate the mass of DMIG elements ?

C Nithish

Hi Team,

Regarding Supper elements conversion

I have created super elements with .pch file using CMSMETH card. How can I know whether the mass and stiffness are completely converted in to reduced form Or Matrix form.

Please help me with this Issue

Thanks & Regards

Hello Nithish, 

Usually for double-checking the superelement creation we run what we call the "Residual Run", where we assign the superelement to the model without the reduced structure and compare it with the full model. In the following tutorial you can check a full workflow for that: https://help.altair.com/hwsolvers/os/topics/solvers/os/hw_reduced_structure_by_superelement_implementation_intro_r.htm

 

Let me know if this helps. Thanks!
