Hi all,
an older topic but I occasionally run into similar issues with non-positive Jacobian elements.
I got a larger model, and when running a static analysis, I get the notification that an element set with non-positive Jacobians was created. I would expect this is a meshing issue and would now change the settings next for the part causing the issue. But the problem I face right now, I cannot locate the elements which cause the error. Is there an easy way of finding these?
For larger element sets, it is straightforward to click on the set and the selection is highlighted in the model. My current model has only 3 of these defective elements.
I simply cannot find these elements in my model being highlighted. So, I have tried to locate the actual elements in the Calculix keyword editor with the intention to get the element if and then use the query tool to locate the issue. But the automatically created data is hidden here and I haven’t found a way to expand the selection.
Is there a way to expand the hidden data in the keyword editor (maybe even manipulate it while we are at it 
or is there another way of locating the elements belonging to this automatically created set?
Many thanks for your insights!
