Thermal and Fluid Analysis: Getting Started with SINDA/FLUINT

What do I need?

  • Computer: You will need a PC compatible computer or HP work station conforming with specified system requirements.
  • Compiler: You may choose a PC version of SINDA/FLUINT based on which Fortran compiler you own: Compaq Visual Fortran version 6.6 or newer, or the Intel Visual Fortran version 9.1 or newer. Alternatively, if you lack either of those compilers, a version of SINDA/FLUINT with a built-in compiler is also available for the PC.
  • Software: Be sure to download the latest version of SINDA/FLUINT from the SINDA/FLUINT download page. If you are interested in the 30-day demo version, please download from the demo web page.
  • License: You will need a current SINDA/FLUINT user license (SINDA.lic). If you downloaded the 30-day demo, a demo license was emailed to you. To purchase a license or obtain a 30-day demo for the HP platform, please contact C&R Technologies.
  • User Interface: SINDA/FLUINT is an ASCII based code. For creating input decks you will either want a good text editor or one of our graphical user interfaces (GUIs) such as Sinaps or Thermal Desktop. Links to free or low-cost text editors are available on our Links Page.

How do I install SINDA/FLUINT?

  • Installing SINDA/FLUINT: To install the software, you must have Admin privileges. Simply double-click on the installation file to begin the installation process. Follow instructions in the installer to complete the installation. If you are working on a network you will probably need to contact your system administrator.

How do I install the license file?

  • Acquiring the license file: If you downloaded the PC-based 30-day demo, you should have received an email containing the license information (save the email as text format for use when installing the license). If you purchased a PC version, you should have received a license file from a sales representative. If you installed the HP version you will need to contact C&R Technologies for a license.
    • If you need a license file for the PC, please run the Licenser Manager Utility under Start>Programs>SindaFluint>License Manager. Click "Request License File", fill out the subsequent forms, and email or fax the information per the instructions.
  • Installing the license file: If you have received a license file from C&R Technologies simply place it in the 'sindafluint/bin' directory of the install location (typically c:/program files/cullimore and ring/). If you have the email response for the 30-day demo download, you can install the license using the License Manager Utility. The manager is accessed through Start>Programs>SindaFluint>License Manager. Click "Install License Files" and follow the instructions. When you are asked to browse for the file, you will need to browse to the license file you received from our sales representative or to the text version you saved of the email you received when you downloaded the 30-day demo. If you are installing on an HP, you will receive instructions for license file installation from our sales department.

Running SINDA/FLUINT

  • Running SINDA/FLUINT: When you installed SINDA/FLUINT the Run SINDA/FLUINT utility was automatically installed if you are running on a PC. This utility can be access through the start menu under Start>Programs>SindaFluint>Run SindaFluint
  • Verify installation: To verify the installation of SINDA/FLUINT and your license file, we recommended you run one of the sample problems. Open the Run SindaFluint utility as stated above. For the input file, browse to the samples directory in the SINDA/FLUINT installation directory and click on "balloon.inp". The file name and path should now appear in the Input File text field. Click the
  • Run SINDA/FLUINT button to launch the model. You should see a processor status window appear. At the completion of the run, you will find the results of the run located in the same directory as the input deck. If the run terminates in errors, you may have problems associated with the installation.

I have installed SINDA/FLUINT and the license, what next?

  • User's Manual: When you installed SINDA/FLUINT the User's Manual was automatically installed if you are running on a PC. You can access it through the start menu under Start>Programs>SindaFluint>Sinda help. If you are running on an HP work station you can download the manual. Take some time to review the User's Manual, especially sections 1, 2, and 4 prior to getting started.
  • Tutorials: Download our tutorials. These tutorials will walk you through sample problems with guidance for making various modeling decisions. The tutorials are available in two formats, one ASCII based and the second using Sinaps as a GUI. We recommend all new users work through these tutorials before starting a thermal or fluid analysis task of their own.
  • Sample Problems: In addition to the SINDA/FLUINT User's Manual we offer an extensive "Sample Problem Appendix". This document is available on the install CD but can also be downloaded from our web site. The Sample Problem Appendix provides a wide assortment of sample problems with detailed discussion of various thermal and fluid analysis options and how best to make appropriate modeling decisions.We recommend all users look through these sample problems. Input decks associated with each sample problem are installed in the "sample" directory located in the SINDA/FLUINT installation directory.

Training Classes

  • SINDA/FLUINT Class Notes: The class notes for our standard SINDA and FLUINT classes and the Advanced Design class are available for download from the web site. We recommend users download these training notes and review them thoroughly. These notes provide an overview of the program structure and guidance for usage. The associated lab notes can also be downloaded.
  • Training Opportunities: We offer training classes for all of our products. It is strongly recommended that all new users attend one of our training classes. The classes, although based on training notes available for download, provide a significant amount of information and instruction not included in the training notes. For more information about the available training classes please visit our Training web page. We also offer custom training.
  • Mini Topic Classes: C&R Technologies offers a variety of short online topic based classes which are free to the user. You review the class listing and register for these classes at our web site.
  • Heat Transfer Reference Books and Education: Although the SINDA/FLUINT User's Manual is extensive, it alone will not provide the necessary background required for creating quality thermohydraulic models. Creating a good model requires educated assessments of how best to model a system to achieve the desired results. This can only be achieved with a strong background in the principles of heat and mass transfer, thermodynamics, and fluid flow.

Installation and User Support

  • For support we recommend you start with our Online Knowledge Database. This forum based database has search capabilities to help you find answers to your questions. You can also post new topics to get answers to your questions.
