Sum of the results from a multi-panel ERP analysis

Neil Hall

I am running an ERP analysis in which I have multiple panels (PANELG).  I am able to get the ERP results for the individual panels form the punch file.  But I would like to be able to get a results for the sum of all of the panels. -thanks

Hi Neil,

For PUNCH file format, the total ERP of all panels is output by OptiStruct automatically. The corresponding area of each panel is also output in the PUNCH file. Please check comment 10 from this link: https://help.altair.com/hwsolvers/os/topics/solvers/os/erp_io_r.htm?zoom_highlight=erp

Using HyperGraph, you can manually calculate sum of ERP results by simply adding them. 

Using HyperView, you can create derived results to add up contour of each ERP results.

Thanks.
