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.

The following compiler is required:

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.

Note:  Intel Parallel Studio XE 2011 Updates 0 through 9 contained a bug that causes SINDA to fail.   Only updates 10-13 work with SF6.0

Also see  Intel Visual Fortran System Requirements

The Intel compiler requires Microsoft Visual Studio or Visual Studio Shell (free) to be installed. Check the Intel system requirements to see which versions of Visual Studio are supported. 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.

Evaluations: Please contact CRTech to learn how to evaluate CRTech software if you do not already have the Intel compiler.

dispersed vs. coalesced front

Tuesday, June 26, 2018, 1-2pm PT, 4-5pm ET

This webinar describes flat-front modeling, including where it is useful and how it works. A flat-front assumption is a specialized two-phase flow method that is particularly useful in the priming (filling or re-filling with liquid) of gas-filled or evacuated lines. It also finds use in simulating the gas purging of liquid-filled lines, and in modeling vertical large-diameter piping.

Prerequisites: It is helpful to have a background in two-phase flow, and to have some previous experience with FloCAD Pipes.
