When exporting to ANSYS ICEM CFD format, these rules are followed:
Note
The series of examples that follows this list illustrates many of the rules listed here.
• To achieve unique ANSYS ICEM CFD part names in the ANSYS ICEM CFD format files, a unique integer is suffixed to all ANSYS Workbench part/body names.
• A single body part in ANSYS Workbench will appear as <part_name>_<part_index> in the ANSYS ICEM CFD format files.
• A multibody part in ANSYS Workbench will appear as
<part_name>_<part_in-dex>/<body_name>_<body_index> in the ANSYS ICEM CFD format files. The / character denotes hierarchy.
• Bodies that are in a multibody part in ANSYS Workbench are put into an ANSYS ICEM CFD assembly.
The structuring in the ANSYS ICEM CFD format files reflects the part/body structure present in ANSYS Workbench.
• As long as they are not contained in Named Selections, faces that are shared between bodies in the same multibody part in ANSYS Workbench are put into separate ANSYS ICEM CFD parts. This type of shared face is named according to the bodies having the face in common, with the body names separated by the # character.
• Entities that are contained in a Named Selection are put into a separate ANSYS ICEM CFD part.
• For each body, an ANSYS ICEM CFD Material Point is created and put into the corresponding ANSYS ICEM CFD part. The names of Material Points have the suffix _MATPOINT.
• If a mesh has been generated, it is exported along with the geometry. In such cases, these additional rules are followed:
– As long as they are not contained in a Named Selection, node/line/surface mesh cells are associated with the corresponding geometry part/body in ANSYS ICEM CFD.
– As long as they are not contained in a Named Selection, volume mesh cells are associated with the Material Point part.
– Mesh cells that are associated with geometry entities that are contained in a Named Selection are associated with the ANSYS ICEM CFD part that corresponds to that Named Selection.
The first example is a model consisting of four separate single body parts in ANSYS Workbench. The single body parts are named fluid1, fluid2, fluid3, and fluid4. The table below shows the geometry in ANSYS Workbench and the corresponding part names that will appear in ANSYS ICEM CFD:

A model consisting of four separate single body parts named:
FLUID1_1 fluid1
FLUID2_2 fluid2
FLUID3_3 fluid3
FLUID4_4 fluid4
The figure below shows the model after it was meshed in the Meshing application:

Next, the model was exported from the Meshing application to ANSYS ICEM CFD format. In the figure below, the corresponding .prj file has been opened in ANSYS ICEM CFD. Notice the names that are as-signed to the various entities in the ANSYS ICEM CFD format file:
• Each body/part name has been suffixed with a unique integer to distinguish it from similarly named bodies/parts. (Note that in this example, part_name is equal to body_name.)
• Each single body part in ANSYS Workbench appears as <part_name>_<part_index> in the ANSYS ICEM CFD format files. For example, the part named fluid1 in ANSYS Workbench has a part name of FLUID1_1 in ANSYS ICEM CFD, which appears as FLUID1_1_1 in the ANSYS ICEM CFD format files after the
part_index is added.
• For each body in the ANSYS Workbench file (Fluid1, Fluid2, Fluid3, Fluid4), a Material Point has been assigned (FLUID1_1_1_MATPOINT, FLUID2_2_1_MATPOINT, FLUID3_3_1_MATPOINT, FLUID4_4_1_MAT-POINT).

The second example is a model consisting of one multibody part in ANSYS Workbench. The multibody part, which is named Part 4, contains four bodies named fluid1, fluid2, fluid3, and fluid4. The table below shows the geometry in ANSYS Workbench and the corresponding part names that will appear in ANSYS ICEM CFD:

A model consisting of one multibody part named Part 4, containing four bodies named:
PART_4_1/FLUID1_3 fluid1
PART_4_1/FLUID2_2 fluid2
PART_4_1/FLUID3_1 fluid3
PART_4_1/FLUID4_4 fluid4

Next, the model was exported from the Meshing application to ANSYS ICEM CFD format. In the figure below, the corresponding .prj file has been opened in ANSYS ICEM CFD. Notice the names that are as-signed to the various entities in the ANSYS ICEM CFD format file:
• Each body/part name has been suffixed with a unique integer to distinguish it from similarly named bodies/parts.
• Each multibody part in ANSYS Workbench appears as
<part_name>_<part_in-dex>/<body_name>_<body_index> in the ANSYS ICEM CFD format files. For example, the fluid1 body in Part 4 in ANSYS Workbench has a part name of PART_4_1/FLUID1_3 in the ANSYS ICEM CFD format files.
• The bodies that are in the multibody part in the ANSYS Workbench file (fluid1, fluid2, fluid3, and fluid4) have been put into an ANSYS ICEM CFD assembly named Part_4.
• The faces that are shared between the various pairs of bodies have been named FLUID2_2#FLUID1_3, FLUID3_1#FLUID2_2, and FLUID3_1#FLUID4_4.
• For each body in the ANSYS Workbench file (fluid1, fluid2, fluid3, fluid4), a Material Point has been as-signed (FLUID1_3_MATPOINT, FLUID2_2_MATPOINT, FLUID3_1_MATPOINT, FLUID4_4_MATPOINT).

The third (and final) example involves a model for which four Named Selections are defined in the DesignModeler application. The model is meshed in the Meshing application, exported to ANSYS ICEM CFD format, and opened in ANSYS ICEM CFD.
The first figure shows the model after it was meshed in the Meshing application.

The next four figures show the entit(ies) in the model that are contained in each of the four Named Selections. In the figure below, the Fluid1_Fluid2 Named Selection is highlighted.

In the figure below, the InterfaceSolidFluid2 Named Selection is highlighted.

In the figure below, the SharedEdge Named Selection is highlighted.

In the figure below, the SharedVertices Named Selection is highlighted.
Figure 19: SharedVertices Named Selection
Next, the model was exported from the Meshing application to ANSYS ICEM CFD format. In the figure below, the corresponding .prj file has been opened in ANSYS ICEM CFD. Notice the names that are as-signed to the various entities in the ANSYS ICEM CFD format file:
• Each body/part name has been suffixed with a unique integer to distinguish it from similarly named bodies/parts.
• The bodies that are in the multibody part in the ANSYS Workbench file (Solid, Fluid1, and Fluid2) have been put into an ANSYS ICEM CFD assembly named Part_1.
• The face that is shared between SOLID_1 and FLUID1_2 has been named SOLID_1#FLUID1_2.
• Because Fluid1_Fluid2, InterfaceSolidFluid2, SharedEdge, and SharedVertices are all Named Selections in the ANSYS Workbench file, each of them has been put into a separate ANSYS ICEM CFD part.
• For each body in the ANSYS Workbench file (Solid, Fluid1, Fluid2, Solid), a Material Point has been as-signed (SOLID_1_MATPOINT, FLUID1_2_MATPOINT, FLUID2_3_MATPOINT, and SOLID_2_1_MATPOINT).
