TRNSYS Suite

TRNSYS consists of a suite of programs: The TRNSYS Simulation Studio, the simulation Engine (TRNDll.dll) and its executable (TRNExe.exe), the Building input data visual interface, and the Editor used to create stand-alone redistributable programs known as TRNSED applications.


 * A TRNSYS Project File (*.tpf) is created with the Simulation Studio, a graphical interface to place and define the components in your workspace. This *.tpf is than converted into the TRNSYS input File *.dck which is called deck file. This file contains all the information on the simulation but in a text file without graphical information. You can also convert a *.dck into a *.tpf but you have to rearrange the components. With TRNEdit, an editor that can be used to create or modify TRNSYS input files (*.dck), a variation of parameters can be performed and this altered deck files are created. All *.dck files are finally executed with TRNExe, the TRNSYS Simulation Engine.


 * TRNEdit can be used to create TRNSED applications. With TRNSED a simplified simulation tool with a graphical interface is created out of an *.dck file and can be used as an planning tool. TRNSED are redistributable applications for users without TRNSYS experience or TRNSYS license.


 * TRNBuild is used to enter input data for multizone buildings. A building description file, *.bui file, is created and includes all information like building structure details, windows optical properties, heating and cooling schedules.
