Possible disadvantages of CFDTool

  • Limited Standalone Functionality
    CFDTool heavily relies on MATLAB, meaning users must have an appropriate MATLAB license, which could limit standalone use and increase costs.
  • Performance for Complex Simulations
    For highly complex simulations and large-scale problems, CFDTool might not perform as efficiently compared to more specialized CFD software packages.
  • Feature Limitations
    Although capable of handling a variety of simulations, it may not offer the depth of features for extremely specialized CFD tasks when compared to industry-standard solutions.
  • Cost
    While relatively affordable, the costs associated with necessary MATLAB licenses can make it a less attractive option for users looking for completely standalone and cheaper alternatives.

  • Having problem with setting up project with external lib
    I'm not sure if this is correct place, since my issue is most likely cmake related rather than c++, but I would like to ask anyway. So I'm trying to set up a project, which is new to me (this was usually done by someone else already). I would like to add the 3rd party library gmsh to the setup, but my CMake seems to incorrectly (or not all) link the lib. Source: over 1 year ago
  • Help With Self Study - Computational Physics
    Depending on what you are planning on trying to do. Goma and OpenFOAMare both free to download and use. You can create a mesh with gmsh for free. Source: over 2 years ago
  • Looking to build a PC for Computational fluid dynamics - Budget around $2000 CAD
    Mostly for work. I need to run some CFD models (OpenFOAM -https://openfoam.org/). But I also need to do pre-processing to create the models. I will use YADE (https://www.yade-dem.org/) and GMSH (http://gmsh.info/) for this. I think that for OpenFOAM it is more important to have good processors but for YADE and GMSH I think that I will also need a decent GPU. Source: over 3 years ago
  • Triangular meshing based on color gradient
    I tried Gmsh with the script from Prof Geuzaine, and it work pretty well. Http://gmsh.info/ Script: Http://geuz.org/photos/cg/cg.geo. Source: about 4 years ago
