*ADMAPOL, file=$path
Data format:
One line with 2 parameters
IGR ANG
Status :
Optional
Restriction :
A group must have been previously defined
Purpose :
To define an added mass coefficient function of arc length and direction
Details :
Parameter | Description |
---|---|
IGR | Group identification number of the line |
ANG | Reference angle in degrees |
The file has the following format:
Number of angles
List of angles
Curv. Abscissa 1 CAdm at angle 1 ... CAdm at angle N
Curv. Abscissa 2 CAdm at angle 1 ... CAdm at angle N
Curv. Abscissa 3 CAdm at angle 1 ... CAdm at angle N
...
Curv. Abscissa i CAdm at angle 1 ... CAdm at angle N
For example :
2 ! number of angles
25 90 ! list of angles
0 1.0 1.0 ! Curv Absc / Adm at angle 1 / Adm at angle 2
100 1.2 1.1
200 1.2 1.1
1000 1.2 1.1
Note
All angle values are in degrees. Note that the reference frame is the local vector (d1,d2)where the added mass is applied. The structure acceleration direction (ang_fs) is evaluated in each location in the local frame. The angle is then used to interpolate the added mass coefficient using (ang_fs-ANG).
