*CMADPOL,FILE=Filename

Data format:

One line with 2 parameters, as follows:

IGR ANG

Status:

Optional

Restriction:

A group must have been previously defined.

Purpose:

To define a coefficient for moment induced by fluid velocity as a function of arc length and direction in air.

Details:

Parameter	Description
IGR	Group number of the line
ANG	Reference angle in degrees
FILE=Filename	Path and name of the file listing the moment loads coefficient function of the curved abscissa and angle.

Note

All angle values are in degrees. Note that the reference frame is the local vector (d1,d2) of each node where the drag is applied. The fluid- structure velocity direction (ang_fs)is evaluated in each location in the local frame. The angle is then used to interpolate the moment coefficient CmZ using (ang_fs-ANG).

File format:

The file has the following format:

  Number of angles
  List of angles
  Curv. Abscissa 1    Cmz at angle 1 ... Cmz at angle N
  Curv. Abscissa 2    Cmz at angle 2 ... Cmz at angle N
  Curv. Abscissa 3    Cmz at angle 3 ... Cmz at angle N
  ...
  Curv. Abscissa i    Cmz at angle i ... Cmz at angle N

For example:

  2                 ! number of angles
  25 90             ! list of angles
  0 1.0 1.0         ! Curv Absc / Cmz at angle 1 / Cmz at angle 2
  100 1.2 1.1
  200 1.2 1.1
  1000 1.2 1.1
