Meshing

High-quality meshes, controlled sizing

Generate triangular surface meshes and tetrahedral volume meshes with intelligent sizing control, global or locally refined. Built-in quality assessment, visualisation and automated repair mean every analysis starts from a reliable, optimised mesh.
Intelligent CAD cleanup

Geometry handling

Intelligent CAD cleanup

Detect and heal intersections and penetrations automatically. Smart Selection recognises similar faces so you apply settings across regions in one click.
  • Semi-automatic defeaturing of chamfers, fillets and holes
  • Define boundary patches directly on geometry
  • Volume extraction to derive fluid domains from solids
Record once, run on everything

Automation

Record once, run on everything

Automate repetitive meshing through the integrated Python interface: operate in the GUI while the recorder captures every step as Python. Generalise the script and process multiple geometries with a single command, ideal for batch processing and parametric studies.

FAQ

Preprocessing, answered

shonMesh is a mesh pre-processing software designed to prepare, clean, and mesh complex geometries efficiently. It enables users to transform raw CAD data into high-quality meshes ready for simulation.

shonMesh offers comprehensive geometry editing and cleanup, a robust meshing engine for generating triangular surface and tetrahedral volume meshes, and fast export to standard mesh formats as well as the shonX product family.

shonMesh includes a powerful set of geometry tools such as Boolean operations, transformations, and repair functions. Key simplification capabilities include automatic feature removal (defeaturing) of elements like holes and fillets, midsurface extraction for thin structures such as metal sheets, and face merging to reduce model complexity. Additional mesh cleanup tools ensure mesh integrity by resolving issues like duplicated or non-manifold faces.

shonMesh integrates a built-in Python interface and console to automate and customize workflows. Users can execute scripts, record interactive GUI actions, and convert them directly into Python code for reuse. This makes it easy to automate repetitive tasks, streamline batch processing, and significantly increase overall workflow efficiency.
