The Basic TRNSYS 18 Package

When you purchase TRNSYS, whether a new purchase or an upgrade, you will receive the following:

  • The Simulation Studio - a graphical front-end that houses all aspects of the TRNSYS simulation procedure.
  • TRNEdit - a specialized solution for turning your simulation into a stand alone, distributable application.
  • TRNBuild - a graphical input program for describing multizone buildings.
  • TypeStudio - a graphical interface and Fortran compiler specially designed for writing and integrating new TRNSYS Types.
  • FORTRAN source code for all* components used by TRNSYS.
  • Electronic versions of all TRNSYS reference and tutorial materials.
  • Technical support from TESS for as long as you own TRNSYS. Limited support for previous versions is available.
  • Free online updates to the TRNSYS package.
  • Subscription to the TRNSYS email group for information and sharing of ideas.

* Two proprietary features exist in the multi zone building model, these are for active layers and internal windows, users receive all non proprietary multizone building source code.

  • Technical support from TESS for as long as you own TRNFlow
  • Free online updates to TRNFlow

TRNSYS thermal mutlizone building model, type 56, requires air flows between zones as input values. However, in natural ventilation systems these depend on the wind pressures and the inside and outside temperatures. To account for this situation, a coupling with an air flow model is absolutely necessary. TRNFLOW integrates the multi-zone air flow model COMIS into the type 56. An internal solver, optimized for this task, iterates in each time step between the two models until their solutions are consistent. The existing GUI TRNBuild was extended in such a way that data for the air flow model can be entered. Thus a user-friendly handling of the coupling is assured. With TRNFLOW, a immense step forward has been made for building simulation with TRNSYS.

Order Processing

TESS is able to send the license file and links to download orders once payment is received. Once TESS receives payment, the order is shipped within the next business week. TESS can accept purchase orders (and thus send the license file and download information prior to receiving payment) but only if arrangements are made ahead of time.
