Wind Velocity Definition

[paulo.chambel.maretec@taguspark.pt]

Dear Nuno,

you have two ways of defining the wind velocity.

Option 1 - You can define the wind velocity using as input the wind velocity components X (m/s, west-east) and Y (m/s, south-north);

Option 2 - You can define the wind velocity using as input intensity (m/s) and direction (degrees, meteorological convention). In this case you have also to define the properties \"wind velocity X\" \"wind velocity Y\" and in each of this two properties you nedd to impose the following options
FILE_IN_TIME : NONE
REMAIN_CONSTANT : 0
In this case the model will use the wind intensity and the direction to compute the components X and Y of the wind;

Option 1 - EXAMPLE:

<beginproperty>
NAME : wind velocity X
UNITS : m/s
DESCRIPTION : calculated wind velocity X
FILE_IN_TIME : NONE
REMAIN_CONSTANT : 1
DEFAULTVALUE : 1.
TIME_SERIE : 1
OUTPUT_HDF : 1
<endproperty>

<beginproperty>
NAME : wind velocity Y
UNITS : m/s
DESCRIPTION : calculated wind velocity Y
FILE_IN_TIME : NONE
REMAIN_CONSTANT : 1
DEFAULTVALUE : 0.
TIME_SERIE : 1
OUTPUT_HDF : 1
<endproperty>

Option 2 - EXAMPLE:

<beginproperty>
NAME : wind modulos
UNITS : m/s
DESCRIPTION : meteoIST wind velocity
FILE_IN_TIME : NONE
DATA_COLUMN : 2
DEFAULTVALUE : 5
REMAIN_CONSTANT : 1
TIME_SERIE : 1
OUTPUT_HDF : 1
<endproperty>

<beginproperty>
NAME : wind angle
UNITS : degrees
DESCRIPTION : meteoIST wind angle
FILE_IN_TIME : NONE
DATA_COLUMN : 3
DEFAULTVALUE : 315
REMAIN_CONSTANT : 1
TIME_SERIE : 1
OUTPUT_HDF : 1
<endproperty>

<beginproperty>
NAME : wind velocity X
UNITS : m/s
DESCRIPTION : calculated wind velocity X
FILE_IN_TIME : NONE
REMAIN_CONSTANT : 0
DEFAULTVALUE : 0.
TIME_SERIE : 1
OUTPUT_HDF : 1
<endproperty>

<beginproperty>
NAME : wind velocity Y
UNITS : m/s
DESCRIPTION : calculated wind velocity Y
FILE_IN_TIME : NONE
REMAIN_CONSTANT : 0
DEFAULTVALUE : 0.
TIME_SERIE : 1
OUTPUT_HDF : 1
<endproperty>

Hi!

Wind direction must be given like this

0º = from North
90º = from East
270º = from West
180º = from South

wind velocities are computed like this:

WindVelocityX= WindModulus* cos(WindDirection * PI / 180.)
WindVelocityY= WindModulus* sin(WindDirection * PI / 180.)

Luis

Hi,

Yes.

Best regards,
