Singularities in FEM results!

Hello Everybody,

I am working with Pro mechanica, I am seeing singularity in my results. what is meant by singularities? It's the peak stress as for I know, but still I could not understand exactly. Can anyone give me a clear vision to that.

A singularity is a point, usually with a load applied which means that the stress is undefined or infinite.

If you have a singularity, the analysis cannot converge, because decreasing the element size or increasing the polynomial order will keep increasing the calculated stress, with no limit.

Did you try to search for "singularities" in the Help Center ?

The explanation found in the Help Center is quite clear.

Thank you so much!
