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 Icon 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)
