System Requirements


Operating System

  • 64 bit Windows 7, 8, or 10

Fortran Compiler

Since SINDA/FLUINT allows user logic and generates a unique executable each time it is run, you MUST have a copy of the correct compiler on each machine in order to run it.

If you wish to run an evaluation version of SINDA/FLUINT, you must download the version of SINDA/FLUINT that has a built-in compiler.

For the production version (for purchased licenses of SINDA/FLUINT), the following compiler is required:

Note: Only Intel Visual Fortran Composer XE 2011 for Windows is required, users do not need to purchase Intel® Parallel Studio XE for Windows for use with SINDA/FLUINT.

FloCAD online training

Class times: May 2 & 4 from 10am to 2pm MT

Cost: $425

This online class will provide an introduction to fluid modeling components within FloCAD. The class will be held over a 2-day period, with daily sessions running approximately 4 hours each. The class uses a mixture of lecture, demonstrations, and self-paced tutorials to allow attendees to practice building fluid system models and interpreting results. The presentations will comprise 2 - 3 hours of each session, and the instructor will be available during the remainder of the time for questions during tutorials. Attendees must have basic working knowledge of SINDA and Thermal Desktop as these topics will not be covered but their usage is required for FloCAD.

Using Sinaps? It is not too soon to get started with TD/FloCAD!

This webinar describes the process for converting from Sinaps to Thermal Desktop (TD) and FloCAD. This process includes using an exporter which works with Version 6.0 of the CRTech tool suite (expected to be released in May of 2017).

Come learn about the basics of TD/FloCAD, including many compelling features not available in Sinaps. The webinar will also cover how to manage the transition period, during which you may be using both programs simultaneously. This is also a chance to ask questions.
