Simulation at zero wind speed situation

Dear team,
I am new in CFD with weak mathematical background. I have a basic query.
Is CFD simulation (Reynolds-averaged non-hydrostatic Navier-Stokes) possible at zero wind speed (u=0) situation?

Thank you …

Hi, and welcome to the forum!

In principle I would say that yes, this is possible. But, why would it make sense to have no flow? There must be another action that drives the movement of fluid, for example:

  • Pressure difference
  • Buoyancy
  • Momentum sources, such as fans, blowers, impellers, etc.

Thank you for your reply…
I understand what you point. But here I specifically want to know if the model can be initiated with zero wind speed (U=0)
