OBJ in het kort
OBJ
OBJ survived because plain-text mesh data and broad importer support made it a comfortable fallback across decades of 3D tools.
MSH in het kort
MSH
Gmsh developed MSH as its native mesh exchange and storage format for geometry-to-mesh workflows, finite element modeling, and post-processing, and later evolved the format across multiple major versions while preserving legacy compatibility.

Wanneer je elk formaat gebruikt
When to use OBJ
- Your source file is already in OBJ.
- Preserve source expectations before exporting to MSH.
- OBJ is commonly used in cad workflows.
When to use MSH
- Your target workflow expects MSH.
- Improve delivery compatibility with MSH.
- MSH is commonly used in cad workflows.
Veelgestelde vragen
Why convert OBJ to MSH?
Convert to MSH when preparing simulation meshes for finite element, CFD, or multiphysics workflows that rely on Gmsh-compatible geometry and physical groups.
It is especially useful as a handoff format between mesh generation, solver preprocessing, and research-oriented numerical simulation pipelines.
What changes when converting OBJ to MSH?
This conversion changes how the format behaves in downstream tools and delivery environments.
What should I review after converting OBJ to MSH?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
