The Simulation Modeling Toolkit (https://smtk.org/) is a set of libraries for simulation pre-processing. You can process geometric models, discretizations of those models (meshes), add attributes like boundary conditions, write simulation input decks, and even submit jobs.

The Pulse Physiology engine is a C++ library that simulates human physiology that will drive medical education, research, and training technologies.

iMSTK (http://www.imstk.org/) is a free & open source software toolkit written in C++ that aids rapid prototyping of interactive multi-modal surgical simulations.

Computational Model Builder (https://computationalmodelbuilder.org/) is a suite of applications built on ParaView and SMTK to help you prepare and submit simulations.

Discussion about this site, its organization, how it works, and how we can improve it.

SENSEI (https://sensei-insitu.org) is a framework that lets large-scale simulations to provide their state to analysis, visualization, and I/O tasks in situ—obviating the need for large output files.
