1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-dateANSYS模型导入ABAQUSANSYS模型导入ABAQUSANSYS模型导入ABAQUSSYS软件的参数化建模（APDL）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。（其中部分内容参考了SIMWE上的精华贴） 首先在ANSYS编写AP

2、DL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,NNode,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

3、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,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
