Grid generation

The output interfaces which are described in this manual use the following files: Structured grids can be created with the HEXA-Mesher. These structured grids (single or multi-blocks) can be converted to unstructured grids in the AI*Environment using the following menu options: After successful transformation, the unstructured domain file is located in the project directory. By default, the unstructured grid resulting from this conversion is called struct_merge.uns. Unstructured grids can be created directly with the HEXA-Mesher (Unstructured), the TETRA-Mesher, the QUAD-Mesher and the GLOBAL-Mesher. The extended topology file, the family-topology file and the boundary conditions file are automatically created in the grid generators.

Boundary Conditions

Under the Output menu, select a solver/format. Then click on the "BC" icon. A window opens up allowing to define boundary condition on the mesh families. These are solver specific.

Note that boundary conditions on curves will only be applied if the curves have been projected properly in HEXA.
 

Interfaces

The standard output interfaces can either be called from the AI*Environment or from a shell or command window. To call the translator from the AI*Enviroment, use the following menu entries: All translators are located in the directory $ICEM_ACN/icemcfd/output-interfaces. To call a translator from a shell or command window, simply type the path and name of the translator, followed by its necessary arguments.

Each translator supports one or more mesh generators. These are indicated in the following sections immediately after the translator name with the abbreviation "T" for the TETRA-Mesher, "S" for the HEXA-Mesher Structured, "U" for the HEXA-Mesher Unstructured, "Q" for the QUAD-Mesher and "G" for the GLOBAL-Mesher.
