LS-DYNA environment

LS-DYNA boundary conditions

The tables list the boundary conditions (loads, constraints, and simulation objects) that are currently supported in the LS-DYNA solver environment.

Command	LS-DYNA keyword	Description	Additional information
Acceleration	*LOAD_BODY_	Defines body force loads due to a prescribed base acceleration.	Constrained keywords for rigid body creation (LS-DYNA)
Constrained Keywords	CONSTRAINED NODE SETCONSTRAINED_NODAL_RIGID_BODY*CONSTRAINED_EXTRA_NODES	Defines connections and motions for a rigid body.	Constrained keywords for rigid body creation (LS-DYNA)
Initial Axial Beam Force	*INITIAL_AXIAL_FORCE_BEAM	Pre-loads beam elements to a prescribed axial force.	Initial forces on beam element axes (LS-DYNA)
Initial Stress	*INITIAL_STRESS_SECTION	Preloads a cross-section of solid elements to a prescribed stress value.	Initial stress (LS-DYNA)
Initial Velocity	INITIAL_VELOCITYINITIAL_VELOCITY_GENERATION	Defines the initial velocity of a body in an impact analysis.	Initial velocity (LS-DYNA)
Rigid Wall Definition	*RIGIDWALL_PLANAR	Designates a surface in the model as a rigid wall for impact testing analysis.	Rigid wall definition (LS-DYNA)
Rotation	*LOAD_BODY_GENERALIZED	Defines body force loads due to a prescribed angular velocity.
Single Point Constraint	*BOUNDARY_SPC	Defines constraints on selected boundary nodes.	Single point constraints for boundary nodes (LS-DYNA)
Contact	*CONTACT_	Models different types of contact.	Contact (LS-DYNA)
