Damping (Spring Material)
From the Damping type list, select Loss factor, Viscous damping, Damping constant per reference area, or Total damping constant. For thin layers on 2D geometries, it is also possible to enter the Damping constant per reference length dL.
When choosing Loss factor, from the Loss factor type list select Scalar (Same for all components) or Individual components.
For Scalar (Same for all components) enter a single Loss factor for spring ηs, which is used to multiply all values of the spring matrix or spring force vector.
For Individual components select Isotropic, Diagonal, or Symmetric, then enter values or expressions for the Loss factor for spring ηk. The loss factors act on the corresponding components of the spring matrix or spring force vector. If you select Isotropic, the effect is the same as when you select Diagonal and enter the same value for all diagonal elements.
When choosing Viscous damping, enter the Normal viscosity ηb and the Shear viscosity ηv.
When choosing Damping constant per reference area, select Isotropic, Diagonal, or Symmetric, then enter values or expressions for the Damping constant per reference area dA.
When choosing Damping constant per reference length, select Isotropic, Diagonal, or Symmetric, then enter values or expressions for the Damping constant per reference length dL.
When choosing Total damping constant, select Isotropic, Diagonal, or Symmetric, then enter values or expressions for the Total damping constant dtot.
