The upper wall "movingWall" is moving in parallel at 1 m/s and the other walls "fixedWalls" are stationary, and we solve the flow without turbulence model. There is no inflow or outflow of fluid, and the calculation is performed as a 2-dimensional problem with a single mesh in the Z direction.

Model geometry Model geometry

The meshes are as follows.

The calculation result is as follows.

Flow velocity (U) Flow velocity (U)
Pressure (p) Pressure (p)

We can see that a vortex is generated.
