Getting Started

What hardware and software do I need?

Computer: All CRTech software runs in the Windows operating system on a computer meeting the minimum system requirements.

CRTech Software: Thermal Desktop® is a geometric thermal modeler that operates in a powerful CAD environment. The underlying solution engine for Thermal Desktop is SINDA/FLUINT. RadCAD® is an optional Thermal Desktop module for radiation heat transfer within the thermal model or between the model and the environment. FloCAD® is another optional Thermal Desktop module for fluid modeling. TD Direct® is a powerful finite element mesher that works operates within SpaceClaim and creates an interface with Thermal Desktop. RadCAD, FloCAD, and TD Direct are all installed with Thermal Desktop and activated with license files.

Please see the Product Selection Guide for more information, or contact our sales department.

Third Party Software: A full product version of SINDA/FLUINT (as opposed to a trial version) requires Intel Visual Fortran. Thermal Desktop operates within AutoCAD. TD Direct operates within SpaceClaim. CRTech is a reseller of all of this software, so everything can be purchased together.

License: You will need a license for each part of the software you want to enable. FloCAD, RadCAD, and TD Direct are installed with every instance of Thermal Desktop, but they are only enabled with different license files. Contact CRTech to purchase a license.

How do I install the software?

See our Installation Instructions.

What learning resources are available to me, and how do I get support?

User Manuals: CRTech products install user manuals with SINDA/FLUINT, Thermal Desktop, and TD Direct. They can be accessed through the start menu: Start > All Programs > (SindaFluint or Thermal Desktop). The TD Direct manual is included in the Thermal Desktop folder from the Start Menu.

Tutorials: The Thermal Desktop, RadCAD, FloCAD, and TD Direct User Manuals include tutorial sections. The tutorials start with the basic operations of our software and gradually increase in complexity. The necessary working files for these tutorials are installed with Thermal Desktop in the folder C:\Program Files\Cullimore and Ring\Thermal Desktop\Tutorials. To use these tutorials they will need to be copied to a location not in Program Files.

Sample Models: CRTech offers a Samples and Applications Forum providing sample problems available to registered customers and evaluators. These sample problems are examples of how to use CRTech software for specific applications.

Training Classes: We offer training classes on all of our products. It is recommended that all new users attend one of our training classes. Although based on training notes available for download, these training classes provide a significant amount of information and instruction that can't be captured in training notes. We offer standard training classes where anyone can attend, or we can also provide specific training for a single organization. For more information, see our Training page. Some of these training classes have been recorded and are available on our recorded videos page.

Topic Classes: CRTech offers a variety of free short, online, topic-based classes. These classes are slightly more advanced because they cover a single topic in more detail. These classes are announced on our website and through newsletters. Recordings for some of these classes are available on our recorded videos page and notes are available upon request.

Recorded Videos: We have recorded several videos to help explain how to use our software.

Technical Support: If you need help, please start with the product user manuals. The Thermal Desktop manual provides information on the graphical user interface, compared to the SINDA/FLIUNT manual which provides in-depth information on the modeling details and methods. If you cannot find the information you need in the manuals, visit our community forum. After all, your question may have already been asked and answered by another user. If your question is still unanswered, please contact the support group. Support tickets may be conveniently created and transmitted from within Thermal Desktop through the Help menu.
