Spring Elements > Stiffness parameters
Input or modification of the spring constants Cx, Cy, Cz, CMx, CMy, CMz of Linear Spring Element as well Compression-Only Springs and Tension-Only Springs.
For Compression-only springs the effective spring constant in the XL-direction is Cx for negative forces Fx (spring in compression), and zero for positive Fx.
For Tension-only springs the effective spring constant in the XL-direction is Cx for positive forces Fx (spring in tension), and zero for negative Fx.
Any specified spring constants apart Cx are universally valid for both, compression-only springs as well as Tension-only springs (values Cy, Cz, CMx, CMy, CMz).
