The PLOT3D file type refers to a format for structured grid data that was popularized by NASA's CFD visualization software of the same name (Ref. 40).
For database Import, 1D, 2D and 3D single and multiblock meshes are supported. ASCII, Binary, and Unformatted file formats can be imported into Fidelity Pointwise in either Single or Double precision.
Note that Fidelity Pointwise can import PLOT3D files containing i-blank data but that data will be discarded. For database import only curves and surfaces will be supported. Therefore, for 3D, volume meshes are ignored and their constituent boundary surface meshes imported instead. Structured surface meshes will be imported as database surface entities.
PLOT3D file import will default to the endian value the file was written in. The swap bytes attribute is available for this format.
