General Questions

Does Ultraliser create volumetric meshes?

No. The current version of Ultraliser creates two-manifold watertight triangular surface meshes that can be used to create tetrahedral and hexahedral meshes using third-party applications like TetGen¹, QuarTet², GMsh³, and CGAL⁴.

Does Ultraliser read volumetric meshes?

Yes. Ultraliser can read tetrahedral meshes created with TetGen and QuarTet to generate corresponding surface mesh models and volumes.
