Sample Geometric and Field Complexities
The grid generator can handle local geometry and field complexities including:
Singular points
Small scales
Small angles
Disparate length scales
Different scales orientation / directionality
"Mega" Geometries and Meshes
"Mega" geometries pose additional requirements to the grid generator. Some common issues are the existence of thousands of panels and "dirty" CAD. Solutions to these issues include:
Automatic setup
Automatic identification of similar parts (e.g. pipes)
Automatic and repeated manual CAD cleaning actions
"Mega" meshes are required in applications such as LES, multi-stage turbomachinery, aircraft take-off and landing, etc. and have been achieved with over a billion elements via use of the following features:
High speed element generation
Parallel / Multi-zone
Multi-core
Exascale
