Abstract:
We introduce a flexible, variable resolution tool for interactive
resampling of computational fluid dynamics
(CFD) simulation data on versatile grids. The tool and
coupled algorithm afford users precise control of glyph
placement during vector field visualization via six interactive
degrees of freedom. Other important characteristics
of this method include: (1) an algorithm that resamples
any unstructured grid onto any structured grid, (2)
handles changes to underlying topology and geometry,
(3) handles unstructured grids with holes and discontinuities,
(4) does not rely on any pre-processing of the
data, and (5) processes large numbers of unstructured
grid cells efficiently. We believe this tool to be a valuable
asset in the engineer’s pursuit of understanding and
visualizing the underlying flow field in CFD simulation
results.
