I applied the procedure that you described, but where do I get the result? Does it come in a separated file?
To make it clear, I don't want to see the contour for a group of specific elements, instead, I am interested in the sum of all strain energy in the part.
For instance, the procedure I am using now is to extract the strain energy of all elements in a .cvs file, and then sum all the values in Excel. However, this procedure is time-consuming when you have a large model, so I am looking for a simpler procedure to obtain this single scalar value.
