Flow 3D wind and snow simulation

I will provide house plan with and without extension. You will need to sketch the buildings and import it into flow 3D to simulate wind from East and look at how snow will collect.

Simulation has to be done in Flow 3D and a picture I will provide.

Look at attached files. I have provided the plans of the house I need to be sketched and simulated. There is also an example of another house which has the simulation I want.
