In 1994, ESA initiated a study into what is still one of the biggest problems facing the space thermal analysis community: the need for reliable data transfer between the different analysis tools. The outcome of that study was the start of the journey that would lead to the development of STEP-TAS and TASverter.

ESA sees STEP-TAS as the key technology for the harmonisation of space thermal analysis tools and data exchange between national agencies and industrial groups using different tools.

TASverter is a general converter for models used in Thermal Analysis for Space. It has “reader” modules for converting information from the native file formats of a number of [space] thermal analysis tools into an internal data structures, and “writer” modules to convert from these data structures into the native file formats of a number of [space] thermal analysis tools. The internal data structures are based directly on the STEP-TAS protocol.

Note: TASverter is NOT a converter for STEP files from CAD!

TASverter was developed to replace some older tool-to-tool converters that involved a lot of duplicated code and were difficult to maintain.

TASverter became a cutting-edge technology demonstrator to show the reality of model data conversion and exchange using STEP-TAS. TASverter has been used extensively within ESA to verify and validate the development on the underlying STEP-TAS protocol using real-world models written for different thermal analysis tools. TASverter paved the way for the implementation of STEP-TAS interfaces in the commercial space thermal analysis tools.

The ultimate goal of the TASverter and STEP-TAS development was to create a tool independent standard for data exchange, and to transfer the interface software and lessons learned to the analysis tool vendors themselves. STEP-TAS interfaces are now available in some of the space thermal analysis tools, such as ESATAN-TMS and THERMICA.

The TASverter development team has easy access to systems running Windows 7, Windows XP, and CentOS Linux, and has a large test suite for verifying that TASverter runs correctly on those systems. TASverter has not been built or tested on other Windows or Linux platforms.

The previous release of TASverter from 2007 does not run on Windows 7 and uses STEP-TAS v5.2. It is provided here for historical reasons only.
