乘员保护/行人保护相关功能
· *LOAD_PYRO_ACTUATOR/*DATABASE_PYRO
· Calculates nodal/segment forces from a pyrotechnic piston actuator without the need to model the chamber/piston
· Input: nodes/segments, mass flow curve, chamber cross section area, etc
· Pressure tube sensor is used to deteck pedestrain collision
· New solution method options
- MTD=0: Standard Galerkin (CG) for Acoustic
- MTD=1: Discontinuous Galerkin (DG) for Acoustic Equations(Less diffusive than CG)
- MTD=2: DG for Isothermal Euler Equations <推荐>(More accurate for large amplitudes
Handles shocks and rarefaction waves)

先进碰撞相关仿真方法
· 可压溃梁Crushable beam in LS-DYNA
· A beam element to simulate the behavior of beam type structures
· input Force/moment vs. displacement/rotation along local r, s and t
· 可以非常方便的将整车结构约束为一整个刚体而使得相冲突的关键字失效,在满足特定条件后恢复。方便加快某些工况(如翻滚、自动驾驶)的车体碰撞前的姿态计算。
· *CONSTRAINED_NODAL_RIGID_BODY together with *DEFORMABLE_TO_RIGID allows users to rigidize a few parts during a specified period of time. However rigidizing the whole vehicle for pre-crash simulation could be challenging since it will conflict with existing rigid body or constraint definitions.
· *CONSTRAINE_NODAL_RIGID_BODY_MASTER detects all conflicts and turns off all of them until the master rigid body is turned off by *SENSOR_CONTROL.
