Data format :
One line with 2 parameters
IGR ANG
Status :
Optional
Restriction :
A group must have been previously defined
Purpose :
To define an inertia coefficient (Cm) 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 Cm at angle 1 ... Cm at angle N
Curv. Abscissa 2 Cm at angle 1 ... Cm at angle N
Curv. Abscissa 3 Cm at angle 1 ... Cm at angle N
...
Curv. Abscissa i Cm at angle 1 ... Cm at angle N
For example :
2 ! number of angles
25 90 ! list of angles
0 1.0 1.0 ! Curv Absc / Cm at angle 1 / Cm 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) of each node the wave inertia force is apllied. The wave 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).
