Keyword type: model definition
With this option the force-velocity relationship can be defined for dashpot elements. There is one required parameter ELSET. With this parameter the element set is referred to for which the dashpot behavior is defined. This element set should contain dashpot elements of type DASHPOTA only.
The dashpot constant can depend on frequency and temperature. Frequency dependence only makes sense for *STEADY STATE DYNAMICS calculations.

For each temperature a set of lines can be entered. First line in the first set:
Example: *DASHPOT,ELSET=Eall 1.e-5
defines a dashpot constant with value ![]() for all elements in element
set Eall and all temperatures.
 for all elements in element
set Eall and all temperatures.
