In addition to the generation of block interiors, existing grids may be modified to reflect geometric changes that are defined by an automated design and optimization cycle. Volume grid modification is provided in the form of arclength-based TFI and 3D grid deformation. The program runs in the batch environment, which allows for integration directly into the design loop.
Program flow is controlled via user input commands.
The input commands and the baseline volume grid are generated once outside the design loop. With this information, the code generates modified CFD volume grids based on new surfaces that are created in the design and optimization cycle. The code is portable and has been tested on Unix platforms, including the Silicon Graphics Iris and Hewlett Packard workstations and Cray mainframes. This work was done under contract with Computer Sciences Corporation in the Langley Geometry Laboratory.
