Abstract
One of the most used algorithms to generate hexahedral meshes for extrusion volumes
is the multi-sweeping method. The algorithm decomposes the geometry into
many-to-one sub-volumes and then meshes each sub-volume separately.
However, the quality of the final mesh depends on the decomposition process. First,
the location of inner nodes created during the decomposition process may induce bad
quality elements. To avoid this drawback, we propose a three-stage decomposition
process to locate those nodes. Second, the imprinting process is not robust when
dealing with non-planar surfaces. For this reason, we introduce the new concept of
the computational domain. The computational domain is a planar representation of
the levels of the geometry. In this way, we improve the operations needed to perform
imprints.
