What Pictures Are Wind turbine technician Obsessed with Everyday

What do wind turbine design technician do every day? What are the simulations they talk about all day long?  Since wind turbines are closely related to air flow, many studies will use CFD (Computational Fluid Dynamics) software for calculations, which can often generate some colorful GIFs, and the industry also nicknames CFD Colorful Drawing.  But for engineers, in most cases, these pictures have very limited meaning.
