System Requirements

General Requirements

Operating System

  • 64 bit Windows 8 or 10

Minimum Memory

  • 8 GB RAM (16 GB recommended)


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.

Prerequisite Software

  • Fortran Compiler
    • Intel® Visual Fortran Version 11.1.048 or newer, or Intel® Visual Fortran Composer XE for Windows or Parallel Studio XE for Windows
      Note: Only the Composer Edition of any version is required. The Professional or Cluster editions will also work, but those editions add features that are not required by SINDA/FLUINT.
    • Review Intel Visual Fortran System Requirements
    • Known Issues
      • Intel Parallel Studio XE 2011: Updates 0 through 9 contained a bug that causes SINDA to fail. Only updates 10-13 work with SINDA/FLUINT 6.0 or newer.
      • Intel Parallel Studio XE 2018:  The initial release of this version has issues with the Visual Studio shell not working. Recommend installing 2018 update 1 or newer.
  • Microsoft Visual Studio
    The Intel compiler requires MS Visual Studio to be installed. Check the Intel system requirements to see which versions of Visual Studio are supported for a particular version of the Intel compiler.

    • Integration with Intel Parallel Studio XE versions 2017, 2018, early 2019: These installers provide an integrated shell version of Visual Studio which will suffice. For these Intel installations, if Visual Studio is not found on the computer, the installer will automatically install the shell version. No purchase of the Microsoft Visual Studio is required. If Visual Studio is already installed on the computer, Intel will integrate with it and not install the shell.
      • Shell installation supporting software requirements
        • Intel Parallel Studio XE 2017 (2013 shell) requires Microsoft SDK 8.1 to be installed
        • Intel Parallel Studio XE 2018 (2015 shell) requires Microsoft SDK 10 to be installed
        • Intel Parallel Studio XE 2019 inital release, update 1, and update 2 (2015 shell) requires Microsoft SDK 10 to be installed
    • Integration with Intel Parallel Studio XE version 2019 update 3 or newer: These installers do not provide an integrated Visual Studio shell. For these installations you must install MS Visual Studio.
      • MS Visual Studio Community
        • For classroom learning environments, academic research, or for contributing to open source projects, Visual Studio Community can be used at no cost.
        • For non-enterprise organizations, up to five users can use Visual Studio Community.
        • Enterprise organizations (>250 PCs or > US$1 million annual revenue), no use is permitted beyond the open source, academic, classroom training.
      • MS Visual Studio Professional or Enterprise
        • For enterprise organizations which do not meet the Community requirements.

Introduction to Two-phase Flow

September 24, 2-3pm MDT

This webinar introduces basic concepts in two-phase flow modeling including quality, void fraction, flow regimes, slip flow, pressure drops and accelerations, and heat transfer.

No knowledge of CRTech software is required. However, references to the corresponding FloCAD features will be made to assist users of that product.
