Physhub is a modeling, testing and hosting platform for physical models of intelligent systems. It is based on OpenModelica and other standard and community supported solutions. It provides a browser-based editing, simulation, and analysis environment for scientists and engineers who design and test their control algorithms and intelligent systems using design automation tools. It provides users an integrated workflow - build diagram of mathematical or physical systems using libraries of components in various domains (electrical, mechanical, thermal, etc.) and simulate them in all in one tool that always stays in sync. It provides reusable components (compatible with Modelica Standard Library) so you build your project upon the work of others. One of the key benefit of this product is collaboration - collaborative workflows to tear down information silos with modern version control, commenting, and real-time design reviews. Whether you are a student working on a course project or an engineer validating your next innovation idea, this browser-based block diagram editing tool and cloud-native simulation tool makes designing and analyzing your plant model or controller an absolute breeze.
