;18 point cell with variable angles

;

;this model attempts to simulate using pads rather than point loads for the mirror supports

;  dr is 1/2 the size of the mirror rest pads radially -- 0.0246 is 5mm for a 16in mirror

;  da converts dr to degrees at the rim, later adjusted ro the radius of the supports

;  r1 is the radius of the pad center for pads on the inner ring

;  r2 is the radius of the pad center for pads on the outer ring

;  a2 is one-half of the angle between the outer pairs of points in degrees

;  f1 is the relative force on the inner points
