TASverter: a converter for space thermal model and data exchange
Note: TASverter is NOT a converter for STEP files from CAD!
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.
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.
Terms and Conditions
TASverter is provided free of charge by ESA, subject to the copyright and disclaimer at the bottom of this page. The latest version of the executables can be downloaded by clicking on the entry in the table below. Although you do not need to request a username and password to be able to download TASverter, you will be asked to provide your name and a valid e-mail address to which further download instructions will be sent.
The 2017 beta release of TASverter contains a few improvements on primarily the TRASYS interface, a STEP-TAS viewer and a TMM converter for ESATAN-TMS and SINDA/Fluint. The other already existing GMM interfaces are not updated and are only kept available for legacy reasons. For most GMM interfaces it is advised to use the STEP-TAS interface in the relevant tool as this will be more up-to-date. For more detailed information on the beta version of TASverter please refer to the Release Notes.
The 2019-07-19 beta release contains a number of bug fixes and small enhancements, in particular:
- a few improvements for the TRASYS reader in handling angle tolerances
- a few bug-fixes for the STEP-TAS geometry viewer
- improvements on TMMverter in processing SINDA/Fluint models, for instance handling LOADQ statements internally, DIV and DPV handling
The TASverter development team has easy access to systems running Windows 10, Windows 7 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.
In addition to TASverter, a new set of standalone converters for Thermal Desktop is also provided in the download list below. Since the 6.1 release of Thermal Desktop (May 2019) a new API has facilitated these conversions. The single zip file contains converters from STEP-TAS to Thermal Desktop and from Thermal Desktop to STEP-TAS. The zip file also includes usage instructions.
The Thermal Desktop converters have been tested on Windows 10 using a large number of new test cases and real models. Nonetheless, they remain beta versions until more extensive testing is complete. Eventually these converters may be merged into TASverter.
