Gmsh Meshing

When to Use This Skill

Use this skill when you need to:

  • Generate surface panel meshes for BEM hydrodynamic solvers
  • Create structured (transfinite) or unstructured meshes
  • Script parametric geometries with .geo or Python API
  • Perform boolean/CSG operations via OpenCASCADE kernel
  • Import and remesh STEP, STL, or IGES geometry
  • Control mesh density with size fields (distance, threshold, background)
  • Export meshes to AQWA (.DAT), WAMIT (.GDF), Nemoh, or general formats (MSH, STL, VTK, UNV)
  • Batch-generate meshes from the command line
