Ansys Fluent

Solver Ansys Fluent
Type of meshunstructured mesh
Dimension2D and 3D

The Ansys Fluent interface creates a Fluent or Fluent Meshing mesh file from an unstructured mesh, with the following grid sections:

SectionIndex
Comment 0
Dimensions 2
Nodes 10
Cells12
Faces13
Periodic Shadow Faces18
Zone Section39

The mesh file can be written in ASCII or binary format.


Note:  The Fluent output interfaces are separate executables that operate on project files that have been saved to disk. This means you will need to save the project, particularly the mesh, part boundary conditions, and/or properties files before sending output to the solver. If your mesh is large and you are concerned about memory limitations and do not want the mesh loaded twice into memory (the editor and the output interface), you can then unload the mesh and proceed with the output based on the saved mesh file.


Creating the Ansys Fluent Input File

The translator writes the Ansys Fluent input file using an unstructured mesh file and its boundary condition file. To create the Ansys Fluent file, select Ansys Fluent in the Output Solver list and click Apply. After generating the mesh, boundary conditions can be defined. Supported boundary conditions are:

Volumefluid, porous, solid
Surfaceaxis, fan, interior, mass-flow-inlet, outflow, periodic, porous-jump, pressure-inlet, pressure-far-field, pressure-outlet, radiator, symmetry, velocity-far-field, velocity-inlet, wall

Select the  Write input option in the Output tab. A window will open to allow the specification of the files to be translated into the Ansys Fluent format.

Ansys Fluent Options

Specify the following:

  • the grid dimension

  • the scaling factor for the coordinates in the geometry file (optional)

  • ASCII or binary output

  • ignore couplings (yes or no)

  • the name of the boundary condition file

  • the name of the Ansys Fluent file

Creating the TGrid Input File

The translator writes the TGrid input file using an unstructured mesh file and its boundary condition file.


Note:  TGrid is the same as Fluent Meshing and supports only surface mesh.


To create the TGrid file, select TGrid in the Output Solver list and click Apply. Select the  Write input option in the Output tab. A window will open to allow the specification of the files to be translated into the TGrid file.

TGrid Options

Specify the following:

  • the grid dimension

  • the name of the boundary condition file

  • the name of the Fluent Meshing file
