OpenSeesRT

Fast nonlinear finite element analysis.

xara is a library for nonlinear finite element analysis, implemented in C++ on the OpenSees architecture. OpenSees features state-of-the-art finite element formulations and solution algorithms, including mixed formulations for beams and solids, over 200 material models, and an extensive collection of continuation algorithms to solve highly nonlinear problems.

The OpenSees framework is an open-source project sponsored by the Pacific Earthquake Engineering Research Center (PEER). Documentation of features that are specific to OpenSeesRT, as well as a general reference on OpenSees, can be found in the STAIRLab’s supplementary documentation site, https://xara.so. A gallery of examples is curated by the STAIRlab at https://gallery.stairlab.io.
