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.
The meshes are as follows.
The calculation result is as follows.
We can see that a vortex is generated.
