BioGears® source code is hosted here and will be developed through this public repository to encourage community facing development. In addition, we also support official stable releases. Our latest deployment (found under releases) is still in a beta phase, and is intended to be an intermediate release to showcase the capabilities of the BioGears® Physiology Engine. The current version of the software includes examples of all types of engine interfaces, but does not include all of the functionality or physiologic systems that will be present in the final product. This version of the software is meant to elicit feedback and enhance community involvement in establishing end product expectations.

BioGears® is a C based, open source, multi-platform (Windows, Mac, and Linux), comprehensive human physiology engine that will drive medical education, research, and training technologies. BioGears enables accurate and consistent physiology simulation across the medical community. The engine can be used as a standalone application or integrated with simulators, sensor interfaces, and models of all fidelities.

• Create a publicly available physiology research platform that enables accurate and consistent simulated physiology across training applications
• Lower the barrier to create medical training content
• Engage the community to develop and extend physiology models
• Meet the training needs of the military
• Expand the body of knowledge regarding the use of simulated physiology for medical education

If you'd like to use BioGears in your research, we ask that you cite the following publication:

We have made available to the medical simulation community a large set of burn injury physiology data, hosted on Zenodo. We have listed this dataset under the creative commons 4.0 license so that it be used for any reason you may deem fit. We only ask that any results properly cite the above article and the database DOI:

• Modified Scenario CDM to require Tag around individual actions
• Allowed import of external ActionList and DataRequestList
• Updated CMAKE to minimum 3.20
• Improved various features

• Improved SWIG bindings
• Improved Various Models
