*DAMPCONT

Data format:

An arbitrary number of lines comprising 3 values.

IGR1 IGR2 COEFV

Status :

Optional

Purpose :

To add a contact force based on relative velocity of the two groups.

Restriction :

A contact between both groups IGR1 and IGR2 must have been previously defined.

Details :

Parameter	Description
IGR1	First Group of elements to defined the contact
IGR2	Second group of elements
COEFV	Coefficient on relative velocity (N/(m2/s))

Note

The relative velocity of the two groups is computed for each contact element. For a given element, if the velocity is such that the groups are going towards each other, a lineic force is applied on each group that slows them down.
