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.
