ANSYS模型导入ABAQUS.doc
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,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)*ENDDOAllsel,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,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,NODE,5 *GET,EN6,ELEM,nd,NODE,6 *GET,EN7,ELEM,nd,NODE,7 *GET,EN8,ELEM,nd,NODE,8 *VWRITE,Chrval(nd),',',Chrval(EN1),',',Chrval(EN2),',',Chrval(EN3),',',Chrval(EN4),',',Chrval(EN5),',',Chrval(EN6),',',Chrval(EN7),',',Chrval(EN8)(A8,8(A1,A8)nd = ELnext(nd) *END IF*ENDDOAllsel,all*GET,NumberofNode,NODE,COUNT, , , ,ESEL,S,ENAME,45 !solid45单元 8节点六面体*GET,NElem,ELEM,COUNT, , , , !

最后在ABAQUS中点主菜单FILEIMPORTMODEL,选择要导入的INP文件,在窗口顶部环境栏的MODEL下拉列表中,就会出现与此INP文件同名的模型。ANSYS模型转到ABAQUS模型APDL!ANSYS命令流!将ANSYS模型文件转到ABAQUS模型文件!选中所有单元Allsel,all! 输出节点*GET,NNode,NODE,COUNT, , , , ! 得到当前模型中的总节点数*CFOPEN,Toabaqus,inp*VWRITE('*HEADING')*VWRITE('Fracture Mechanical Analysis of metal crack with FRP')*VWRITE('*NODE,SYSTEM=R')*DO,I,1,NNode*VWRITE,Chrval(i),',',NX(I),',',NY(I),',',NZ(I)(A8,A1,F10.5,A1,F10.5,A1,F10.5)*ENDDOAllsel,all*GET,NumberofNode,NODE,COUNT, , , ,ESEL,S,ENAME,95 *GET,NElem,ELEM,COUNT, , , , !
