DIMENSIONS: Setting Width, Length etc

The dimensions of a belt are:

#rows : The number of (shell) elements across the width.

Width: The total width of the belt. (For #rows >0 each shell is Width / #rows wide.)

Thickness: Shell element thickness.

Length: Characteristic element length (both seatbelt and shell elements).

Clearly the first three refer only to belts that include shell elements. If #rows =0 then the belt becomes seatbelt elements only.
