See [GitHub - pystra/pystra: Python Structural Reliability Analysis · GitHub](https://github.com/pystra/pystra)

An example with FEM program opensees (a structural and geotechnical code to prevent und minimize damages by earthquake) is done.

Reliability python workflow wie PyCCX or PreCICE or others is here possible.

Last some improvements are here done to actual version 1.6..

Mostly interesting for beam or shell analysis to calculate reliability of a part or model.
