*DRAG CHAIN

Specify parameters for drag chain elements.

This option is used to specify the maximum length of a drag chain, the frictional limit between the chain and the seabed, and the weight of the drag chain.

This page discusses:

Required parameters

ELSET

Set this parameter equal to the name of the element set with which this behavior is associated.

Data line for DRAG2D elements

First (and only) line

  1. Horizontal length of chain at slip, ℓ.

  2. Friction limit between the chain and the seabed.

Data line for DRAG3D elements

First (and only) line

  1. Total length of chain.

  2. Friction coefficient.

  3. Weight of chain (per unit length).
