More damper tutorial obstacles...

now I can set one boundary condition but when I "LMB-click into the 3d view...", I end up with a red box (see attachment).

2:
When I continue to create boundary conditions, only the last one created is stored (I checked it using "view > boundary codes" or "simulation > edit boundary conditions")

How can I get hold of the faces of the damper to set the boundary conditions?

Are you by any chance using the "select all visible" option. That would sett all visible faces to the same boundary code.

I added vol but can't select "green" in the new column, the available options are "A <<" and ">> B".

I continued with the default setting "A <<" (whatever that means) and created the mesh as described in the tutorial.
