3.3.3 Inflation Group

Inflation is useful for CFD boundary layer resolution, electromagnetic air gap resolution or resolving
high stress concentrations for structures. The Inflation group of global mesh controls
appears in the Details View when the Mesh object is selected in the Tree Outline. The options in the
Inflation group provide global control over all inflation boundaries.

Figure:

Maximum Thickness: The Maximum Thickness control determines the desired thickness of the
inflation layer. You must enter a value for this control, and it must be greater than 0. The Maximum
Thickness control is applicable only when Inflation Option is Total Thickness.
First Layer Height: The First Layer Height control determines the height of the first inflation layer.
This first inflation layer consists of a single layer of prism elements that is formed against the faces of
the inflation boundary. You must enter a value for this control, and it must be greater than 0. The First
Layer Height control is applicable only when Inflation Option is First Layer Thicknessor Last Aspect
Ratio.
First Aspect Ratio: By choosing the First Aspect Ratio option for the Inflation Option control, you can
control the heights of the inflation layers by defining the aspect ratio of the inflations that are extruded
from the inflation base. The aspect ratio is defined as the ratio of the local inflation base size to the
inflation layer height.
