Damping - dashpots

Damping in Ashes can be modeled as a nonlinear load. A damping factor can be included as a parameter in the Support structure part or in the text file defining the support structure for imported structures (see Support section files).

The damping load is calculated as
$$L = D_f\cdot V$$

  • $$L$$
     is the magnitude of the damping load applied to the node
  • $$D_f$$
     is the damping factor
  • $$V$$
     is the magnitude of the velocity of the node
The damping load is applied in the opposite direction of the velocity of the node.
