It recognizes a system description language in which the user specifies the components that constitute the system and the manner in which they are connected. The TRNSYS library includes many of the components commonly found in thermal and electrical energy systems, as well as component routines to handle input of weather data or other time-dependent forcing functions and output of simulation results. The modular nature of TRNSYS gives the program tremendous flexibility, and facilitates the addition to the program of mathematical models not included in the standard TRNSYS library. TRNSYS is well suited to detailed analyses of any system whose behaviour is dependent on the passage of time. TRNSYS has become reference software for researchers and engineers around the world. Main applications include: solar systems (solar thermal and photovoltaic systems), low energy buildings and HVAC systems, renewable energy systems, cogeneration, fuel cells.</p>

<p style="margin:0px 0px 1.4em;padding:0px">A TRNSYS project is typically setup by connecting components graphically in the Simulation Studio. Each Type of component is described by a mathematical model in the TRNSYS simulation engine and has a set of matching Proforma's in the Simulation Studio The proforma has a black-box description of a component: inputs, outputs, parameters, etc. The Simulation Studio generates a text input file for the TRNSYS simulation engine. That input file is referred to as the deck file.</p>

These models can be based on fundamental principles or formulated from empirical performance data for a given system component. The component inputs and outputs are linked together in a TRNSYS deck file (.dck) to form a large set of algebraic and differential equations describing the entire system required for simulation. TRNSYS decks can also be formatted as TRNSED files (.trd). A TRNSED file is a user-friendly front-end for the TRNSYS deck which allows a non-expert to operate the simulation without knowledge of the details of the syntax required by TRNSYS.</p>
