WHITE PAPER
Preparation of Geometry Models for Mesh
Generation and CFD
NASA's CFD Vision 2030 Study [1] stated that "most standard CFD analysis processes for
the simulation of geometrically complex configurations are onerous." A major factor
contributing to this perception is the preparation of geometry models for mesh
generation, a task deemed a "significant bottleneck" in CFD workflows.
The implication of the word "preparation" is that the geometry models used for CFD
(computational fluid dynamics) – in other words, the shape of the object around and
through which the flow is to be computed – cannot be readily and easily meshed in the
form in which they are provided; they are not suitable. It logically follows that better
geometry model preparation must be provided to the CFD practitioner to remove
geometry model preparation as a significant bottleneck in CFD workflows. The
practitioner's tools for model preparation have to be improved.
