# QuadWithSensitivity Command
|
integer tag identifying an existing parameter. |
|
four nodes defining element boundaries (numbered following a counter-clockwise order around the element). |
|
element thickness (constant). |
|
string representing material behavior. Valid options depend on the nDMaterial object and the corresponding available material formulations. The ‘type’ parameter can be either "PlaneStrain" or "PlaneStress". |
|
tag associated with previously-defined NDMaterial object. |
|
surface pressure (set temporarily equal to zero for DDM-based sensitivity analysis). |
|
element mass density (per unit volume) from which a lumped element mass matrix is computed (optional, default=0.0). |
|
constant body forces defined in the isoparametric domain (optional, default=0.0). |
