After you have generated your volume mesh, you can use the Manage Zones task make additional changes to your cell and/or face zones (such as renaming or merging) prior to proceeding to the Fluent solver. This can especially useful for large models with numerous zones.
Note: Labels and bodies should not have the same name, since doing so would lead to ambiguities. Bodies whose name contains the string 'fluid' will automatically be assigned as fluid regions, however, the same is not true for solids, since that is usually the default name for any body in both SpaceClaim and DesignModeler.
Set the Type of zone to Cell Zone or Face Zone.
Apply type filtering for the zones:
For cell zones, use the Type Filter to filter the list of available objects as Fluid or Solid or All.
For face zones,use the Type Filter to filter the list of available objects as Internal, Fluid-Fluid, Solid-Fluid, Fluid-Solid, External-Solid, External-Fluid, or External.
Apply value filtering for the zones:
For cell zones, use the Volume Filter to only display a list of cell zones within a certain volume.
For face zones: use the Area Filter to only display a list of face zones within a certain area.
You can set either filter to All, Less than, More than, or Equal to the corresponding Area value (for face zones) or Volume (for cell zones). When using the Equal to option, for the Equal within a range of (%) field, specify a percentage range for the volume/area.
Additional filtering options and wildcards are available in the list as well to help in selecting cell zones.
To merge selected cell/face zones:
Select Merge as the Operation.
Specify the portion of the Name of the selected zones that you want to merge, or keep the default name. The task attempts to create an appropriate name. If the target name already exists, then a numerical value will be appended to the name (such as
my_label_1,my_label_2, etc.).For Do you want to merge adjacent faces?, select either Yes or No.
Note: The merging of cell zones also allows you to merge the underlying face zone(s). Zones with face labels (named selections), however, are not supported during the face merge.
To change the prefix of the names of selected cell/face zones:
Select Change Prefix as the Operation.
Use the From field to indicate the prefix that you want to change, and use the To field to indicate what you would like to change the prefix to. The task attempts to change the prefix accordingly. If the target name already exists, then a numerical value will be appended to the name (such as
my_label_1,my_label_2, etc.).
To rename selected cell/face zones:
Select Rename as the Operation.
Specify a new Name for the selected zone. The task attempts to create an appropriate name. If the target name already exists, then a numerical value will be appended to the name (such as
my_label_1,my_label_2, etc.).
Click Manage Zone to apply your changes for this task. Use the Draw Mesh button to display the surface mesh to inspect any zone changes.
