Python package/library for Linear & Non-linear 3D structural engineering finite element analysis

问题

I am looking for a linear & non-linear 3D structural engineering finite element library for Python. Over the internet, I found "Sfepy" is widely known, but I am not sure how to use it. I am new to structural engineering (finite element analysis).

I am basically looking for Stress outputs from the FEM model for profiles and brackets in a construction domain. The following are the features I am basically looking for.

1. Bracket Modelling (3D)
2. Profile Modelling (1D)
3. Fastener Modelling (1D)
4. Spring-Tension/Compression
5. Rigid Elements for connection
6. Temperature Load Application

The output I am looking for is...

All 5 outputs-(Graphs+Values) available for each load type (UDL/Point load/Moment).

1. Axial force
2. Shear force
3. Reaction force
4. Bending moment
5. Displacement
