as far as I know strain is only computed at the element integration points. Hence, no nodal strains.
OK, it still seems odd that if there are no nodal strains, why there is a radio button to list by Node.
Anyway, beyond the List Results dialog box, are there any other ways to get raw stress / strain / displacement by node or element for use in a separate homebrew post-processing script?
I was just trying to help you - I don't write the stuff.....
It looks like a bug to me.
For static study, both strain by node and by element are available. You can define a strain plot by node. There must be something wrong in the "List Selected" dialog box. Before this bug gets fixed in service packs, you might want to try this workaround:
1. Define a strain by node plot.
2. Use Probe/List Selected cmd
3. Select the desired faces and update
4. You get the node index, values, etc at the grid
5. You can save as Excel file or plain text.
