1、ANSYS模型导入ABAQUSANSYS模型导入ABAQUS SYS软件的参数化建模极其方便，而ABAQUS卓越的非线性计算功能使其成为有限元软件中的贵族，如果能整合两者的优势，有限元模拟计算就会相当高效。下面就将ANSYS模型如何导入ABAQUS简单交流一下。 首先在ANSYS编写APDL语言输出模型的节点和单元数据文件。如果直接用ANSYS中的WRITE NODE FILE和WRITE ELEM FILE得到的节点和单元数据文件，数据之间只有空格，没有逗号，不符合ABAQUS的INPUT文件格式要求。输出节点信息的APDL如下： Allsel,all !选中所有 ! 输出节点 *GET,N
2、Node,NODE,COUNT, , , , ! 得到当前模型中的总节点数 *CFOPEN,ansystoabaqus,inp *DO,I,0,NNode *VWRITE,Chrval(i),NX(I),NY(I),NZ(I) (A8,A1,F10.5,A1,F10.5,A1,F10.5) *ENDDO Allsel,all 输出单元信息时要弄清楚单元类型，编写APDL对每种类型的每个单元输出单元编号，各节点的编号。常见的SOLID65和SOLID45、SOLID95单元的APDL输出命令如下： *GET,NumberofNode,NODE,COUNT, , , , ESEL,S,ENAME,
3、65 *GET,NElem,ELEM,COUNT, , , , ! 得到当前模型中的总单元数 !对单元集进行循环 *GET,nd,ELEM,NUM,MIN, , , , *DO,I,1,NElem !得到当前单元的类型 *GET,ENAME,ELEM,nd,ATTR,ENAM !如果是65号(65号单元) *IF,ENAME,EQ,65,THEN !得到该单元的节点编号 *GET,EN1,ELEM,nd,NODE,1 *GET,EN2,ELEM,nd,NODE,2 *GET,EN3,ELEM,nd,NODE,3 *GET,EN4,ELEM,nd,NODE,4 *GET,EN5,ELEM,nd,
