本人新手，正在学LS-DYNA，自己也在照着书上的例子练习，但常常发生错误。在这里借用技术邻这个平台交流学习，分享自己的经验。方便别人发现错误，也及时改正我自己的错误。
分析流程：用ANSYS Mechanical APDL Product Launcher打开ANSYS，注意在打开时选择带有LS-DYNA的license并勾选LS-DYNA模块→在GUI过滤的预前设置处勾选LS-DYNA显示分析→设置单元、实常数并建立几何模型（该粘合的地方需要粘合）→Mesh Attributes进行材料分布处理，然后划分网格→在LS-DYNA Options处创建Part，定义接触类型、时间边界条件、初始速度→设置时间控制、时间步长、能量选项和沙漏控制等→输出K文件，修改K文件，递交求解器求解→用Ls-prepost软件进行后处理，或者用Matlab进行数据处理等。
