*BOUNDARY_SPC_SET
Specifies Fixed Support, Simply Supported, and Fixed Rotation constraints.
Card
NSID = ID of set of nodes to which the boundary is applied.
CID = ID of the associated coordinate system. 0 specifies the global coordinate system.
DOFX = 0 or 1. 0 means that the translation is free and 1 that the translation is constrained along the x direction. It is set to 0 for the Fixed Rotation boundary condition and to 1 for the Simply Supported boundary condition.
DOFY = 0 or 1. 0 means that the translation is free and 1 that the translation is constrained along the y direction. It is set to 0 for the Fixed Rotation boundary condition and to 1 for the Simply Supported boundary condition.
DOFZ = 0 or 1. 0 means that the translation is free and 1 that the translation is constrained along the z direction. It is set to 0 for the Fixed Rotation boundary condition and to 1 for the Simply Supported boundary condition.
DOFRX = 0 or 1. 0 means that the rotation is free and 1 that the rotation is constrained along the x direction. It is set to 0 for the Simply Supported Boundary Condition and to 1 for the Fixed Rotation Boundary Condition when the degree of freedom is fixed in that direction.
DOFRY = 0 or 1. 0 means that the rotation is free and 1 that the rotation is constrained along the y direction. It is set to 0 for the Simply Supported Boundary Condition and to 1 for the Fixed Rotation Boundary Condition when the degree of freedom is fixed in that direction.
DOFRZ = 0 or 1. 0 means that the rotation is free and 1 that the rotation is constrained along the z direction. It is set to 0 for the Simply Supported Boundary Condition and to 1 for the Fixed Rotation Boundary Condition when the degree of freedom is fixed in that direction.
*BOUNDARY_PRESCRIBED_MOTION_RIGID
See *BOUNDARY_PRESCRIBED_MOTION_SET
*BOUNDARY_PRESCRIBED_MOTION_SET
Specifies velocity and displacement boundary conditions.
Card1
ID = ID of set of nodes or part (for rigid bodies) to which the boundary condition is applied.
DOF = 1, 2 or 3 depending on whether the boundary condition is in the x, y or z direction respectively, and is a translational boundary condition.
DOF = 4, 5 or 6 depending on whether the boundary condition is in the x, y or z direction respectively, and is a rotational boundary condition.
Setting 4 is used if the boundary is applied according to a local coordinate system.
VAD = 0 or 2 depending whether the boundary condition is velocity or displacement.
LCID = ID of the curve prescribing the magnitude of the boundary condition. Constant values of velocity are applied as a step function from time = 0. Constant values of displacement are ramped from zero at time = 0 to the constant value at termination time. This is done to make sure that displacements are applied in a transient fashion.
SF = 1.0 (default) scale factor for load curve.
VID = 0 (default). ID of vector that defines the local coordinate system the boundary condition is applied with.
DEATH = 0.0 (default), sets it to 1E28.
BIRTH = 0, the motion is applied from the beginning of the solution.
Card2: not required.
