Simulation Modeling Toolkit (SMTK)

The Simulation Modeling Toolkit ( 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.

Computational Model Builder (CMB)

Computational Model Builder ( is a suite of applications built on ParaView and SMTK to help you prepare and submit simulations.

Pulse Physiology Engine

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

Interactive Medical Simulation Toolkit (imstk)

iMSTK ( is a free & open source software toolkit written in C++ that aids rapid prototyping of interactive multi-modal surgical simulations.
