INNOVATION
A new methodology
for efficient generation of large high-quality tetrahedral and prismatic
meshes for CFD gas turbine combustor and other applications
|
CFD-GEOM, with a direct link to
UniGraphics, accepts true CAD data
without IGES translation and generates
complete unstructured grid systems with
minimal user input

ACCOMPLISHMENTS
Developed software package
CFD- GEOM with:
- Automatic curvature based unstructured
grid generation on trimmed-NURBS geometry models
- Interactive assignment of boundary
and volume conditions, directly on the geometry, configurable for
various flow solvers
- Tetrahedral grid mesher for
large grids (100K-300K cells per minute) based on Delauney and Advancing
Front technique
- Prismatic grid mesher for resolution
of boundary layers based on Advancing Layers Method
- Direct interface to commercial
CAD systems
|
COMMERCIALIZATION
- CFD-GEOM is being marketed as
a stand-alone product for structured and unstructured grids, as
well as in conjunction with CFDRC flow solvers
- Installed at more than 250 organizations
worldwide for a variety of CFD grid applications. The average license
fee is ~$5K
