Can someone guide me on how to obtain strain results in my analysis?"
I am currently using a software tool (e.g., HyperWorks or OptiStruct) to perform finite element analysis. In class, the professor required us to calculate element stresses, strain, and displacement. however, I was able to view stress and displacement results, but I don't know how to enable or view strain results.
