Hey guys

This is my very first post, so I'm pretty excited about it

At first, let me introduce you my project:
I want to simulate a flow around a cube which is positioned in the middle of a small channel with a square profile of 0.1 m and with a length of 0.2. The cube has just an edge length of 0.05 m and the free-stream velocity is 1 m/s.
My purpose is to simulate fluid-structure-interaction; this is why I determined the boundary condition between the channel and the cube as a slip condition. Since the flow is incompressible and turbulent I chose pisoFoam.
I want to check if the cube is being moved by the flow...

I almost went through the tutorials and the user's guide without any remarkable problem (I hope so at least ).

So, I was ready to run my first simulation by creating the mesh using blockMesh but then I received the following errors. As I'm new in this and as I thought I did everything right, I have no clue what went wrong
I hope you can guide me through this

I've also attached the whole case just in case you want to have a look at it
