Input examples

Since NOWS has utilized MATLAB as a numerical calculation engine, inputs are MATLAB-compatible format. Below examples are based on the simulation of three locations.

Example 1 : wind velocity simulation at uniformly distributed locations
4:4:12
4,8,12

Example 2 : wind velocity simulation at non-uniformly distributed locations
4,10,12


Updates

The function of fluctuating wind force calculation is now removed as it required large memory size. Instead, an additional output, mean wind speed (U), is added in the result interface to be downloaded. With this information, one can calculate fluctuating wind force by following expression:
where, F(t) = fluctuating wind force; ρ = air density; CD = drag coefficient; A = tributary area: U = mean wind speed; u(t) = fluctuating wind speed
