Create/Modify Aerodynamic Force

(Template Builder) Build → Forces → Aerodynamics → New/Modify             Shared Dialog Box
Creates or modifies an Aerodynamic Force. Learn about GFORCE: Aerodynamic Modeling.
 
For the option:
Do the following:
Aerodynamics Force Name
If creating an Aerodynamic force, enter a name for it.

If modifying an Aerodynamic force, enter its database name.

Tips on Entering Object Names in Text Boxes.
Application Part 1
Enter the name of the part on which the aerodynamic force will act.
Application Part 2
Enter the name of the part on which the aerodynamic force will act.
Note: You only require to specify this when you have two point property file selected and application of second force on the different part. Possible use case scenario could be 'two body configuration'.
Property File
If creating an aerodynamic force, note that the text box by default contains the file mdids://acar_concept/aero_forces.tbl/aerodynamic_forces_2loc.xml. You can use this file or select another one from your databases.

If modifying an aerodynamic force, specify the property file that contains the coefficient data for the aerodynamic force.

The property files for aerodynamic force are classified into four types as shown in below table:
Property File Type

■Side Force Front
■Side Force Rear
■Lift Front

Also property files contains float parameters which stores constant value for each coefficient.
Location 1 (Always enabled for single point and two point 2D/3D aerodynamic force property file)
Location Dependency
Select one of the following:
With any of the above options, Location defines the initial Cartesian coordinates of the origin of the part's Body Coordinate System (BCS) with respect to the Global Coordinate System (GCS).
If application part 1 is flexible body, select one of the following:
If you select Delta Location From Coordinate, you must specify the node(s) of the flexible body at which you wish to react the attachment loads. The attachment location does not have to be coincident with the selected node(s). Note that you may select more than one node to react the load (C++ Solver only).
Location 2 (Only enabled for two point 2D/3D property)
Location Dependency
Select one of the following:
With any of the above options, Location defines the initial Cartesian coordinates of the origin of the part's Body Coordinate System (BCS) with respect to the Global Coordinate System (GCS).
If application part 2 is flexible body, select one of the following:
If you select Delta Location From Coordinate, you must specify the node(s) of the flexible body at which you wish to react the attachment loads. The attachment location does not have to be coincident with the selected node(s). Note that you may select more than one node to react the load (C++ Solver only).
Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments:
■If recording comments for modeling entities in Standard Interface, your template-based product displays the Entity Comments dialog box.
■If recording comments for any other entity type, your template-based product displays the Modify Comment dialog box.
Learn about Recording Comments.
Select to modify:
■XML File Format property files in the Property File Editor.
While either tool is active, you cannot perform operations in the main window. After exiting either tool, you can resume working in the main window.
Select to view property file information. By default, your template-based product displays this information in the Information window, but you can choose to display the information in a text editor.
