TRNSED : Creating Distributable Stand-Alone TRNSYS Simulations

Introduction
One of the perennial problems with simulating complex energy systems is in communicating the results of a study. Normally, the simulator writes up results in a report and submits it to the clients. Then if the client wants something modified as a result of the analysis, they are forced to go back to the simulator and have them rerun new cases. Arguably the most powerful feature in TRNSYS is a method (called TRNSED) that allows TRNSYS users to share simulation work with non TRNSYS and even non-technical users. For the TRNSYS programmer, the standard TRNSYS input file is relatively easy to read and edit. However, manipulation of the file might be confusing for those not familiar with its syntax. With the addition of a few commands to the TRNSYS input file by the programmer using a specialized text editor called TRNEdit, TRNSED eliminates unwanted details and generates a professional, customized display of selected parameters and inputs. TRNSED provides a refined interface in which selected inputs may be viewed and/or changed and simulations run. TRNSED also offers a parametric simulation capability as well as post-simulation plotting. Detailed help, unit conversion and input checking are also included at the discretion of the TRNSED programmer. The TRNSYS license agreement allows the TRNSYS owner to freely distribute TRNSED, the small TRNSYS executable, and a TRNSED input file to others. The following figure shows just one possibility for a customized TRNSED interface to a TRNSYS simulation.

The figure below shows an example of what might be produced using TRNSED.
