vamseeachanta 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
