Wind - CsCd
CsCd factor is not available in SCIA Engineer (cf art.6.1 from EN 1991-1-4) :
"The structural factor CsCd should take into account the effect on wind actions from the non-simultaneous occurrence of peak wind pressures on the surface (Cs) together with the effect of the vibrations of the structure due to turbulence (Cd).
But there is a little trick to take into account this factor in the software while waiting for its development.
The wind pressure is equal to:
qp * (Cpe*CsCd + Cpi)
[qp*Cpe*CsCd] + [qp*Cpi]
CsCd * qp * [Cpe + (Cpi/CsCd)]
From the version 22 of SCIA Engineer, we can see this qp pressure in the view parameters setting:

A solution could be to:
- Manually calculate the CsCd factor,
- Multiply the qp pressure by CsCd and manually define it :

-
Automatically generate wind loads from this customized pressure, taking care of dividing Cpi by CsCd in the wind generator:
