The Read_Hess_File module allows files in the "Hess" file format to be read into AVS/Express. The Hess file format is used by CFD panel methods. It is also very close to the "PANAIR" format that is used by the North-American Aerospace industry. The module takes the geometry from the Hess file and generates a poly-tristrip that is placed into an Express field. The read_hess user macro enhances the module further by including an user interface and by generating a renderable DataObject. Hess format files typically have a ".n3d" extension.
filename
Name of the Tin .N3D file to be read. The parameter is of type string. This is the only input parameter to the Read_Hess_File module.
out_fld
The output field containing field data constructed from the data present in the Hess file.
out_obj
A DataObject created from the data present in the Hess file, that is suitable for direct connection to a viewer.
The low-level Read_Hess_File module is used in the User Macro read_hess. Additionally, the user macro also uses the ReadHessUI UI Macro.
An example application ReadHessEg is provided, which allows a Hess file to be loaded and allows the data to be mirrored around the X,Y and Z axis. Unfortunately no example data files are available for distribution with this module.
iac_proj/rd_hess/hessmods.v contains the V definition of the Read_Hess_File module.
iac_proj/rd_hess/hessmacs.v contains the V definitions of the ReadHessUI User Interface Macro, the read_hess User macro and the ReadHessEg example application.
The low-level ReadHessMods library containing the module Read_Hess_File does not specify a process. By default the express process will be used.
