modelling for geometry and mesh variants
Mesh
variants:
Meshing attributes (edges, faces, regions) and model properties (solver
boundary conditions are defined with regard to CAD geometry. Due to this
fact, local refinement, changing of boundary layer thickness etc. take just
one click.
The mesh will be generated from scratch, whereas predetermined parameters
(e.g. boundary conditions) for other geometrical objects are preserved.
Small
changes in the geometry model
 |
Meshing
parameters and modelling settings (e.g. OpenFOAM settings) can be
copied from one CAD model to another. |
Abstract
modelling for large changes or completely different CAD geometries
|
|
Abstract modelling is a technique that allows defining the
components of a numerical analysis independent of a specific
geometry. The defined problem is then associated with entities of
the CAD-geometry such as surfaces, regions etc. Applying the
abstract modelling technique, mesh settings, boundary conditions and
solution settings can be associated with very different CAD
geometries. This results in a fast and reliable model generation for
geometry case studies including meshing, boundary conditions and
solver settings. Furthermore, the risk of biasing the design study
by mesh dependency is reduced. |
