A fast and clean interface to the OpenSees framework for finite element analysis.

This is an experimental package that provides an optimized OpenSees Tcl interpreter, as well as a new set of Python bindings that is both idiomatic, and free of global state.

The package may be used as a drop-in replacement for both OpenSees and OpenSeesPy, and generally provides a considerable performance boost.

Python versions 3.7 - 3.11 are supported on Linux.

Note This package is independent of the openseespy library, which is documented in the OpenSees documentation website.

This package is experimental and not yet intended for public use.
