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: Tutorials are an excellent way to get aquainted with the software by starting with the basic operations of our software and gradually increase in complexity. Our tutorials are all located on our community forum. To access these you will need to log into our webiste.

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. Our Tips and Samples webpage provides a convenient filtering system help you find content withing this forum.

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.

Advanced Pipes in FloCAD
Thursday November 14, 9-10am MT (8-9am PT, 11am-noon ET)
This webinar introduces advanced features for FloCAD pipes in addition to working with complex geometry. Complex geometry includes interior fins and surfaces for heat transfer, flow around enclosed objects, annular flow, concentric pipes, and more. FK Locators and TEEs as modeling objects will also be introduced.
Custom Heat Transfer and Pressure Drops
Tuesday November 19, 2-3pm MT (1-2pm PT, 4-5pm ET)
Do you know what the default assumptions are in FloCAD, and whether or not they apply in your situation? Do you know how far you can go past that starting point? The answer: pretty far. There are numerous mechanisms in FloCAD for adjusting factors, scaling uncertainties, and applying different or supplemental correlations. This webinar summarizes the options available to you to customize your flow models to make sure that they apply to each new situation you encounter.
Heat Exchangers: Detailed and System-level
Thursday November 21, 2-3pm MT (1-2pm PT, 4-5pm ET)
This is two webinars in one. The first explains the use and assumptions behind the FloCAD HX system-level modeling object. The second webinar describes detailed-level modeling of complex heat exchanger passages, including application of Compact Heat Exchanger (CHX) methods.
Starting in 2020, we will begin offering Introduction to Thermal Desktop and Introduction to RadCAD as either in-person training or online training, alternating between online and in-person every three months. The training uses lectures and demonstrations to introduce you to basic Thermal Desktop and RadCAD usage. Hands-on tutorials provide practice building models and interpreting results (tutorials are completed by students outside of the online class time).
 
The next training class will be an online format in January 2020:
  • Introduction to Thermal Desktop (and SINDA) - A three-part series on January 14, 16, and 21 from 9am to 12pm, Mountain time
  • Introduction to RadCAD - January 23 from 9am to 12pm, Mountain time
For up-to-date schedules, fees, and policies, visit our Product Training page. To register for the class above, complete our registration form and select "Online" for the Training Format.
 
If you are interested in product training for your company based on your schedule, please contact us to obtain a quote for training between 8-12 attendees. We can come to your facility or the lectures can be presented online. Descriptions of the available classes can be found in our course catalog.
