Total strain energy of a component in Optistruct

I need to obtain a simple scalar value for the total strain energy of my model. However, so far, I have only managed to obtain the strain energy for every single element.

I am using Optistruct profile and running a linear static analysis. I have seen the same topic a few times in the forum, but none of the solutions seems to work for me.

Any help is appreciated.

Hi Joao

Did you try this?

Create an element Set for the part or component you are interested in. If you want the entire model, you can select all the elements of the model

When you are creating ESE card in control cards, change ESE_V1 to SID and call the element set in SID.

This will contour Strain energy for the elements in that particular component.

Check this and let us know

Pranav Hari,

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.

you will get the result in the .h3D file. You can open it in HyperView and change the result type to strain energy

Also, check this pdf document about strain energy summation

Pranav Hari,

It works perfectly now.

The PDF content is exactly what I was looking for, thank you so much.

Thanks! It helped me too. Where can I find more info about this?
