The Basic TRNSYS 17 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.
  • 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.

COMIS 3.2

When you purchase COMIS you will receive the following:

  • The COMIS program
  • The COMIS manual
  • Technical support from TESS for as long as you own COMIS
  • Free online updates to COMIS
  • Access to the COMIS user email group

COMIS is a bulk air flow modeling tool that was originally developed at the Lawrence Berkeley National Labs in Berkeley CA. While freely available, no front end and little support is offered. In 2006, the TRNSYS Studio interface developer (CSTB) modified their TRNSYS Studio so that it functions also as an interface for COMIS. We are pleased to offer this powerful package as an add-on to TRNSYS.

COMIS is now available for download for free from sourceforge.

TRNFlow

When you purchase TRNFlow you will receive the following:

  • The TRNFlow program
  • The TRNFlow manual
  • 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.
