Hardware

General Requirements        
 

Operating System

  • 64-bit Windows 10 or 11

Minimum Memory

  • 32GB RAM (64GB recommended)

SINDA/FLUINT

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
    • The following compilers are compatible with CRTech software
      • 2025 R1: Intel Fortran Compiler Classic 2024 or newer
      • 2024 R1 and R2: Intel Fortran Compiler Classic 2024 or newer
      • 2023 R2: Intel Fortran Compiler Classic 2023 or newer
      • V6.3: Intel Fortran Compiler Classic 2021 or newer
    • The Intel compiler requires one of the following, with support for C++ enabled
      • Build Tools for Visual Studio 2022 or newer
  • See Fortran Compiler compatibility with all recent versions of SINDA/FLUINT

Hardware

  • Storage
    • Basic: Local or network drive required for running case sets. Cloud storage is not supported due to the read/write operations required by the solution engine.
    • Recommended: Solid State Drive (SSD) for better performance.

Thermal Desktop®, RadCAD®, and FloCAD®

Prerequisite Software

  • SINDA/FLUINT, which is the solution engine, must be installed
