在ls-prepost 建立sph模型的详细过程

LS_Prepost 关键操作1. 模型建立立方体模型球体模型起始坐标Part 编号起始节点号:该 Part第一个节点号码粒子密度立方体沿三个坐标轴方向得节点数圆柱体模型球心坐标球体球体半径沿三个坐标轴方向得节点数圆台/锥模型圆柱方向坐标底部中心坐标圆柱半径圆柱高径向节点数,一般设置相同轴向节点数2. 参数定义*DATABASE_FORMAT 计算结果输出格式圆台/锥方向坐标底部中心坐标圆台底部半径圆台高径向节点数,一般设置相同轴向节点数圆台顶部半径数据库IFORM Output format for D3PLOT and D3THDT filesEQ、0: LS-DYNA database format (default),EQ、1: ANSYS database format,EQ、2: Both LS-DYNA and ANSYS database formats、IBINARY Word size of the binary output files (D3PLOT, D3THDT, D3DRLF andinterface files for 64 bit puter such as CRAY and NEC、EQ、0: default 64 bit format,EQ、1: 32 bit IEEE formatRemarks:1、 This option is not available for every platform、 Check LS-DYNA Banner upon executionof the program2、 By using this option one can reduce the size of the binary output files which are created by 64 bits puter such as CRAY and NEC、二进制*DATABASE_EXTENT_BINARY 结果输出控制数据库 NEIPH Number of additional integration point history variables written to the binary data- base for solid elements 、 The integration point data is written in the same order that it is stored in memory-each material model has its own history variables that are stored、 For user defined materials it is important to store the history data that is needed for plotting before the data which is not of interest、给实体单元增加附加综合得点历史变量二进制数据库,综合点数据目得就是储存记忆每个材料模型使它拥有自己得历史变量。对于使用者而言,定义材料对于储存历史数据就是很重要得,在数据储存前需要对其进行描绘。NEIPS Number of additional integration point history variables written to the binary data- base for both shell and thick shell elements for each integration ...
