Post-processing of non-linear bushing strains

Fernando Fuster

Hello,

I'm using a 2020.0 version of HyperWorks and I'm trying to post-process non-linear bushing strains in CBUSH elements using Hyperview. In the contour menu I can select NonlinearStrain(t) but nothing is displayed when I select only the CBUSH for which I want to get the non-linear strains.

I'm running a sol106 in Nastran 2013.1.0 with CBUSH and PBUSHT property card with the KN option to call a compression/force table to simulate a seal. 

Post-processing the op2 result file in Patran (both 2012.2 and 2017.0.3 versions) I'm able to get the non-linear strains in the same CBUSH elements as the ones for which nothing is displayed in Hyperview. 

Is there any way to visualize non-linear strains in 1D elements in Hyperview? 

By the way, what it is plotted in Patran are the elongations, not the strains, but they are called non-linear strains anyway... 

Thanks and regards,

Fernando.
