About:
Gmsh is an open-source 3D finite element mesh generator with a built-in CAD engine for creating complex geometries. It provides a complete meshing pipeline from geometry creation to high-quality mesh generation for various solvers. The tool is highly scriptable and supports multiple file formats, making it essential for computational physics and engineering simulations.
Key Features:
  • Interactive 3D CAD engine with solid modeling capabilities
  • Structured and unstructured mesh generation algorithms
  • Extensive file format support (STEP, IGES, STL, MSH, etc.)
  • Scriptable via Python and native .geo files for automation
Use Cases:
  • Generating computational meshes for CFD and FEA simulations
  • Creating complex 3D geometries from scratch or imported CAD models
  • Converting and repairing meshes for different solvers
Alternatives:
  • Salome – More comprehensive CAE platform but heavier and steeper learning curve
  • Cubit – Commercial alternative with advanced meshing but expensive licensing
  • FEniCS – Focuses on PDE solving rather than dedicated mesh generation
