The interface writes the geometry file following the specification of the Datex, Data Exchange Format, Version 2.1. The geometry file is used to store the geometrical description of a device with some complementary information like the contact locations and the device materials.
The Datex geometry file created with this translator contains the following sections:
The translator writes the DATEX geometry file using an unstructured domain file and its corresponding boundary condition file. To create the DATEX input file, select the translator "DATEX" in the "Output" menu. After clicking "Write input" you can specify options for the DATEX interface:
The interface generates the DATEX file located in the project directory.
Region Material Type:
A "region" in DATEX corresponds to a "domain" in ICEM CFD. So for each domain a material type must be defined. The available material types are:
For a 2D grid, the contacts are defined on the edge boundaries and for a 3D mesh, the contacts are defined on the subface boundaries. No more than one contact per entity (edge or subface) may be specified. A contact is defined by assigning a boundary condition FLAG to an EDGE or a SUBFACE. This FLAG must contain a maximum of 5 characters. The user is free to specify this string of characters. Note that the flags can be typed in upper or lower case.
