rigidDiaphragm
(perpDirn, rNodeTag, *cNodeTags)¶ Create a multi-point constraint between nodes. These objects will constraint certain degrees-of-freedom at the listed slave nodes to move as if in a rigid plane with the master node. To enforce this constraint,
Transformation
constraint is recommended.perpDirn
(int)direction perpendicular to the rigid plane (i.e. direction 3 corresponds to the 1-2 plane) rNodeTag
(int)integer tag identifying the master node cNodeTags
(list (int))integar tags identifying the slave nodes
