Kangaroo simulation won't work.

Hello guys.

I'm relatively new to GH and Kangaroo.

Referring to some tutorials and books, I managed to create this curved bench and now to prepare them for production, I need to planarize them.

There is more work to be done after the planarization but without that it's useless at the moment. So I built the definition ready to simulate the planarization but whatever I do with the values of the forces I used, it doesn't seem to work.

Attached you will see the file. Please if you reply to this, I'd gladly hear a bit more detailed replies since I'm new to this and maybe those quick ways in your mind won't make sense to me. 

Thank you.
