HDF Interface

Solver HDF
Type of mesh multiblock
Dimension 3D


The HDF translator creates an HDF file of structured grid data, with additional features specific to turbmachinery.

Creating the HDF Input Files

The translator writes the HDF input files using a set of structured domain files, a topology file and a boundary condtions file.

To create the HDF input file, "Select solver" → HDF in the "Output" menu. After clicking "Write input " you can specify the following options for the interface: 

All of the grid information is contained in the *.hdf output file. The interface generates this HDF file in the project's directory.

Defining Shaft Pointers

To specify a shaft pointer for a domain:

    1. Choose "Output > Bound Conds" and select the domain for which you want to specify the shaft pointer.
    2. Then press "Add new b.c" and select "Shaft pointer"
    3. Enter the shaft pointer number in the field and press "Accept."

Defining mystery physics boundary conditions

The mystery physics boundary condition is used to pair 2 surface patches as an interface although they are both topologically a "wall".
The first subface is given the Boundary Value "Mystery Physics" with a non-zero value.  The second subface is given the condition
Mystery Physics and must refer to the family name of the 1st subface.

Defining Boundary Conditions

To specify a boundary condition type for a family:

    1. Choose "Output > Bound Conds" and select the subface for which you want to specify the b.c. type.
    2. Then press "Add new b.c." and select one of:
                Wall, Inlet, Exit, or Leak
         from the list of Boundary condition types.
    3. Press "Accept".

- "Interface" boundary conditions (regular, periodic and hgrid) are automatically found topologically in the mesh.
- Any unspecified surface family is defaulted to a "Wall" boundary condition.

Please refer to the General Remarks section for more details on defining boundary conditions.
