Cutting a tetrahedral mesh by implicit surfaces

@inproceedings{RUNKJRM55,
 abstract = { Numerical simulations, such as flow simulation, need a space discretization that set equivalent
media properties to be use in the computation. Geomodels individualize structures that either
segregate rock types or locally impact the rock mechanical properties. Volumetric meshes must
integrate these structures in order to store consistent physical properties. We propose a method to
update volumetric tetrahedral mesh by cutting mesh elements. This work has been developped with
an implicit modeling framework where geological objects are represented as isovalue of a 3D scalar
field. The method starts with a purely tetrahedral mesh and produces a hybrid (i.e. composed of
tetrahedra, prisms, pyramids and hexahedra) unstructured mesh while adding implicit surfaces. It
opens new perspectives for automatic mesh simplification and for incremental structural modeling. },
