AIM Outputs

The following list outlines the FUN3D outputs available through the AIM interface. All variables currently correspond to values for all boundaries (total) found in the *.forces file

Net Forces - Pressure + Viscous:

  • CLtot = The lift coefficient.
  • CDtot = The drag coefficient.
  • CMXtot = The moment coefficient about the x-axis.
  • CMYtot = The moment coefficient about the y-axis.
  • CMZtot = The moment coefficient about the z-axis.
  • CXtot = The force coefficient about the x-axis.
  • CYtot = The force coefficient about the y-axis.
  • CZtot = The force coefficient about the z-axis.

Pressure Forces:

  • CLtot_p = The lift coefficient - pressure contribution only.
  • CDtot_p = The drag coefficient - pressure contribution only.
  • CMXtot_p = The moment coefficient about the x-axis - pressure contribution only.
  • CMYtot_p = The moment coefficient about the y-axis - pressure contribution only.
  • CMZtot_p = The moment coefficient about the z-axis - pressure contribution only.
  • CXtot_p = The force coefficient about the x-axis - pressure contribution only.
  • CYtot_p = The force coefficient about the y-axis - pressure contribution only.
  • CZtot_p = The force coefficient about the z-axis - pressure contribution only.

Viscous Forces:

  • CLtot_v = The lift coefficient - viscous contribution only.
  • CDtot_v = The drag coefficient - viscous contribution only.
  • CMXtot_v = The moment coefficient about the x-axis - viscous contribution only.
  • CMYtot_v = The moment coefficient about the y-axis - viscous contribution only.
  • CMZtot_v = The moment coefficient about the z-axis - viscous contribution only.
  • CXtot_v = The force coefficient about the x-axis - viscous contribution only.
  • CYtot_v = The force coefficient about the y-axis - viscous contribution only.
  • CZtot_v = The force coefficient about the z-axis - viscous contribution only.

Force components:

  • Forces = Returns a tuple array of JSON string dictionaries of forces and moments for each boundary (combined forces also included). The structure for the Forces tuple = ("Boundary Name", "Value"). "Boundary Name" defines the boundary/component name (or "Total") and the "Value" is a JSON string dictionary. Entries in the dictionary are the same as the other output variables without "tot" in the name (e.g. CL, CD, CMX, CL_p, CMX_v, etc.).
