PAERO2 dialog box (Nastran)

Physical Property Table
Name	Defines the name of the physical property table.
Label	Defines the unique numeric identifier for the physical property table.
Properties
Common Properties
Half-Width of a Body	Specifies the reference value for both the radius of the aero body and the radius of the constant width interference tube.
Orientation	Lets you select the direction in the aerodynamic coordinate system in which the aero body is allowed to move in the aerodynamic coordinate system.
Slender Body Half-Width
Slender Body Half-Width	Lets you specify a list of radius values at the end points of the aero body. If you do not specify any values, the software uses the Half-Width of a Body value as the constant radial value for the aero body.
Interference Body Half-Width
Interference Body Half-Width	Lets you specify a list of radius values at the end points of the interference body. If you do not specify any values, the software uses the Half-Width of a Body value as the constant radial value for the interference body.
Aspect Ratio	Lets you specify the aspect ratio (height/width) for the interference body.
Interference Body Theta Array 1
Angular Divisions	Lets you specify a set of theta divisions around the interference body. Enter angle values between 0 and 360 degrees.
Interference Element Set1-Theta Array 1
First Set First ElementFirst Set Last ElementSecond Set First ElementSecond Set Last ElementThird Set First Element****Third Set Last Element	Lets you select the range of interference elements that belong to theta arrays 1, 2, and 3. You can select up to three sets of these elements. For each set, specify the ID value of the first and last elements in the set, For example, to select elements 1, 2, 3, 4, and 5, type 1-5. Note: All elements in these arrays use the specified Angular Divisions
Interference Body Theta Array 2
Angular Divisions	Lets you specify a set of theta divisions around the interference body. Specify these values as angle values between 0 and 360 degrees. All aero body elements that are not included in the interference elements sets use these Angular Divisions.
