Inflation is useful for CFD boundary layer resolution, electromagnetic air gap resolution or resolving high stress concentrations for structures. Inflation is supported for the following mesh methods:
Volume Meshing:
Note: Inflation is supported for the sweep mesh method only when the Src/Trg Selection option is set to either or .
Surface Meshing:
Figure 54: Inflation into Volume Mesh Methods illustrates inflation into the patch conforming, patch independent, sweep, and MultiZone mesh methods respectively.
Defining Global Inflation Controls
The group of global mesh controls appears in the Details View when the Mesh object is selected in the Tree Outline. The options in the group provide global control over all inflation boundaries.
In most cases, the controls in the group apply to both 3D and 2D inflation. Additional information that is specific to 2D inflation is noted where applicable.
Basic options include:
Defining Local Inflation Controls
In addition to setting global inflation controls, you can use local (scoped) inflation controls to apply inflation to specific boundaries. In most cases, the values that you set globally will be populated to the local inflation controls. If you subsequently make changes to the local inflation settings, the local settings will override the global settings. For details, refer to Inflation Control.
Inflation and Mesh Method Controls
For steps to follow to assign inflation depending on the selected mesh method, refer to Inflation Controls. For general information on applying inflation controls in combination with the various mesh method controls, refer to Meshing: Mesh Control Interaction Tables.
