Stiffness | S | The simple spring stiffness per unit area of the specified area object face. [F/L3] | Number |
Spring Type | T | Spring Type: (0=TENSION_COMPRESSION 1=COMPRESSION_ONLY 2=TENSION_ONLY) | Integer |
Axis | A | Optional (normal if not provided) Local Axis being -3, -2, -1, 1, 2 or 3 indicating the area object local axis that corresponds to the positive local 1-axis of the spring. | Integer |
Face | F | Face, This is -1 (Bottom face), -2 (Top face) or a nonzero, positive integer indicating the area object face to which the specified spring assignment applies | Integer |
