The POPINDA interface writes a grid control file GRSDAT and a grid point file GRXDAT for a multiblock mesh in POPINDA input format. The grid control file GRSDAT describes the global block-structure. The grid point file GRXDAT contains the grid coordinates for all blocks.
Solver parameter
Please click on the parameter icon to define the following solver parameter:
- No. of multi-grid levels
- Min. no. of vol. on coarsest level
- reduce grid by no. of levels
- Format of integers in grid file
- Format of reals in grid file
- X-Trans
- Y-Trans
- Z-Trans
- Normalization length
- IWIDTH
- ICOORD
- Standard boundary condition
- BC for not specified faces
Creating the POPINDA
logical file (.log) and grid file (.popform)
The
translator writes the POPINDA files using a multiblock mesh, the boundary
conditions file, the topology file and the POPINDA parameters file. To create
the POPINDA files, select the translator "POPINDA" in the
"Output" menu. After clicking "Write input" you can specify
the following options for the POPINDA interface:
- select the multiblock mesh
- give the name of the topology file
- give the name of the boundary condition file
- option to create only the topology file .log
- give the prefix name of the POPINDA files
The interface generates the POPINDA files located in the project directory.
Defining boundary conditions for POPINDA
The following boundary conditions are supported for surfaces:
·
Wall
·
Far_Field
·
Symmetry
·
Engine (Inlet/outlet)
·
Internal Flow (Inlet)
·
Internal Flow (Outlet)
·
Chimera
·
Singular Lines
·
Actuator Disc
·
Periodic
·
Other
Periodicity
The
interface supports translatory and rotator periodicity. The user needs to
specify the absolute value of ICOMP in the boundary condition settings.
Partial matching Grids
The
interface supports grids with hanging nodes.
Two-Dimensional
Grids
The
user needs to generate a 3D multiblock grid in ICEMCFD with one layer of cells
in k-direction.
