TRNSYS 18.02

TRNSYS is a graphics-based software environment used to simulate the behavior of transient systems. While the majority of extended simulations focus on evaluating the performance of thermal and electrical energy systems, TRNSYS can equally be used to model other dynamic systems such as traffic flow or biological processes.

TRNSYS is made of two parts. The first engine (name of kernel) reads and processes the input file, iteratively solves the system, determines the convergence and system variables of the fragment. This core also provides services such as determining thermophysical properties, matrix inversion, performing linear regression and interacting with external data files. The second part of TRNSYS is an extensive library of components, each of which models the functionality of a part of the system. The standard library includes about 150 models from pumps to multiple buildings, wind turbines to electrolyzers, weather data processors to economical methods. Models are built in such a way that users can modify existing components or write their own and extend the capabilities of the environment.
