Possible disadvantages of OpenFOAM

• Steep Learning Curve
  OpenFOAM requires a significant investment of time to learn and master, as it involves understanding complex physics, programming concepts, and software-specific syntaxes.
• Limited GUI
  Unlike some commercial CFD software, OpenFOAM lacks a sophisticated graphical user interface (GUI), necessitating users to rely on command-line input and scripting for setup and execution of simulations.
• Documentation Quality
  Although community-driven, the documentation can sometimes be incomplete or outdated, making it challenging for new users to find reliable and up-to-date instructions and tutorials.
• Performance Variation
  Performance and stability can vary depending on the specific simulation setup and hardware used, which may require users to conduct extensive testing and optimization.
• Dependency Management
  Installing and maintaining OpenFOAM and its dependencies can be complex, often requiring specific versions of libraries and compilers to ensure compatibility and optimal performance.
