CAD to CFD through Virtual Reality

A gas-burner example (1997)

A CAD package (Pro-Engineer) was used to create a gas-burner geometry and save it into an IGES-format file.

This was then read into the CADFIX package, so as to remove deficiencies and to provide an STL-file output.

The STL file was converted into a PHOENICS-VR geometry file by using the PHOENICS-VR geometry convertor.

PHOENICS-VR Editor then used the geometry file to construct the VR world and to attach CFD attributes.

Then the VR-to-CFD convertor generated CFD settings and saved the geometry in the form of facets for the PHOENICS solver ("EARTH") to use.

Note that this work was done in before PARSOL had enabled non-Cartesian geometries to be fitted into Cartesian grids.

Thereafter the flow-simulation calculation was performed by the PHOENICS EARTH program, and the results wereinspected by way of the VR-VIEWER package.
