18.2.2 Dashpot element library

Products: ABAQUS/Standard ABAQUS/Explicit ABAQUS/CAE

Element types

DASHPOTA Axial dashpot between two nodes, whose line of action is the line joining the two nodes
DASHPOT1^(S) Dashpot between a node and ground, acting in a fixed direction
DASHPOT2^(S) Dashpot between two nodes, acting in a fixed direction

Active degrees of freedom

DASHPOTA: 1, 2, 3. The translational degree of freedom in the 3-direction is not activated in an ABAQUS/Standard analysis if both nodes of the element are connected to two-dimensional entities such as two-dimensional analytical rigid surfaces, two-dimensional beam elements, etc.

DASHPOT1 or DASHPOT2: 1, 2, 3, 4, 5, or 6. If you specify a local orientation for the dashpot, these are local degrees of freedom. Otherwise, these are global degrees of freedom.

Additional solution variables

None.

Nodal coordinates required

DASHPOTA: , ,

DASHPOT1 or DASHPOT2: None needed since there is no geometry associated with these elements.
