POPINDA Interface

Solver

POPINDA

Type of mesh

multiblock mesh

Dimension

2D and 3D

(Return)

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:

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:

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.
