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
