Fluctuating Two Component

Wind speed and direction is read from a text file provided as input. The text file should be on the following format:

  • Line 1 : Number of samples

  • Line 2 : Time step

  • Line 3 : Number of columns (=2)

  • Line 4.. : velocity and direction

The file head may contain an arbitrary number of comment lines starting with '.

Example:

  2048       ' Number of samples \
' Comment line 1                  \
  .50        ' Time step           \
  2          ' Format type     **Head of file**
' Comment line 2                   /
' Comment line 3                  /
' Last comment line              /
  20.0000      180.000
  20.3923      180.500
  20.7822      181.000
  21.1672      181.500
  21.5451      182.000

The time step given on the ASCII file may be different from the time step used in the simulation. The specified wind time series will be re-sampled using the time step applied in the simulation based on linear interpolation. Further the velocities will be scaled by the square root of the scaling factor.

If the read time series is shorter than the length of the simulation, the wind velocity in the last part of the simulation will be set to zero.
