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.

Re: Singularities in FEM results!

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

The explanation found in the Help Center is quite clear.
