Hi there,

An assignment from the course asks me to explore how wind velocity looks like in an ideal block in Solidworks Flow Simulation. The graph posed below is a looking-down view, as four grey building studs make a block. Wind is blowing from left side only, and all other setups that I am aware of are symmetric, but the velocity field is not symmetric at all, as shown in the graph shown below. I am trying to figure out what makes the simulation asymmetric with symmetric setups. Wondering if anyone can help me out

Here are some setup details:

Computational domain is 40m*40m*15m

Block consists of 4 buildings, each of which is 10m*10m*10m

Each building is 10 m away from another closest building, and the building edge is 5 m away from the computational boundary

Fluid is air as external flow

Wind enters horizontally the domain only from the left boundary at the velocity of 6 m/s

Please let me know if any other detail is needed. Thank you!

I would make the domain significantly larger say 10x what you have in all directions. This larger domain will capture the pressure bubble fore and turbulence / re circulation aft. You will also get flow down the front of the building (from ~ center to bottom).

The below publication and anything published by B. Blocken will be helpful to you.
