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

"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)
 
Auto CAD Cleaning

 

 

"Mega" Meshes

"Mega" meshes are required in applications such as LES, multi-stage turbomachinery, aircraft take-off and landing, etc.  Requirements that have to be met for the generation of "mega" meshes include:

Optimum meshes (minimum number of elements for given accuracy - hybrid mesh approach)
 
Parallel / Multi-core grid generation
 
Robustness of grid generation
