The master model structure (20', 20") comprises a base member (2); a plurality of frames (8, 9) mechanically connected to the base member (2); a grid member (14) or a perforated plate attached to pipe members or connection members attached to the frames (8, 9) and a surface attached to the grid member (14) or the perforated plate. The surface comprises a foam layer (42) directly attached to the grid member (14) or the perforated plate and that the foam fills the gabs/holes in the grid member (14) or the perforated plate. |
