Plotting results per element

[bernd]

But I fudge the results to nodes in the script above.
I think the datfilereading section is use ful but only once plotting data per element is avaiable.

For this we would need to plot them in integration points of the FEM element?

As a side note, vtk data structures support element data out of the box (called cell data). So at least storing is super easy. However, i'm unsure how well the freecad implementation for plotting works, I never tested it for cell data. It is considered at some points in the code, like here.

i think averaging integration point per element would be sufficient. This is how most commercial packages do it.

averaged integration point results can introduce big errors. So although it may be ok for illustration purposes, it may not be advisable for engineering/design purposes. It would be really useful to get raw tabulated dat file output for a single element by simply clicking on it.
