Irrelevant in this context |
Cx
|
Damping constant for displacement difference
velocity in (local) x-direction
|
Cy
|
Damping constant for displacement difference
velocity in y-direction
|
Cz
|
Damping constant for displacement difference
velocity in z-direction
|
CMx
|
Damping constant for the rotation difference velocity
around the x-direction
|
CMy
|
Damping constant for the rotation difference
velocity around the y-direction
|
CMz
|
Damping constant for the rotation difference
velocity around the z-direction
|
Alpha
|
(in the element table U)
Exponent for describing an exponential damping
law:
F = sign(v)*C*[abs(v)]**Alpha
- v = displacement or rotation velocity
respectively
- F = force or moment in the damper
- C = respective damping constant
Default: Alpha = 1 (linear damping law)
