Ansys命令流大全（整理）
Ansys命令流大全（整理）1、A,P1,P2,P3,P4,P5,P6,P7,P8,P9此命令用已知的一组关键点点（P1~P9）来定义面（Area），最少使用三个点才能围成面，同时产生转围绕些面的线。
点要依次序输入，输入的顺序会决定面的法线方向。
如果超过四个点，则这些点必须在同一个平面上。
Menu Paths:Main Menu>Preprocessor>Create>Arbitrary>Through KPs2、*ABBR，Abbr,String－－定义一个缩略语．Abbr:用来表示字符串＂String＂的缩略语，长度不超过８个字符．String：将由＂Abbr＂表示的字符串，长度不超过６０个字符．3、ABBRES，Lab，Fname，Ext－从一个编码文件中读出缩略语．Lab：指定读操作的标题，NEW：用这些读出的缩略语重新取代当前的缩略语（默认）CHANGE：将读出的缩略语添加到当前缩略语阵列，并替代现存同名的缩略语．Ext：如果＂Fname＂是空的，则缺省的扩展命是＂ABBR＂．4、ABBSA V，Lab，Fname，Ext－将当前的缩略语写入一个文本文件里Lab：指定写操作的标题，若为ALL，表示将所有的缩略语都写入文件（默认）5、add, ir, ia,ib,ic,name,--,--,facta, factb, factc将ia,ib,ic变量相加赋给ir变量ir, ia,ib,ic：变量号name: 变量的名称6、Adele,na1,na2,ninc,kswp ！kswp=0时只删除掉面积本身，＝1时低单元点一并删除。
7、Adrag, nl1,nl2,nl3,nl4,nl5,nl6, nlp1,nlp2,nlp3,nlp4,nlp5,nlp6 ！面积的建立，沿某组线段路径，拉伸而成。
8、Afillt,na1,na2,rad ！建立圆角面积，在两相交平面间产生曲面，rad为半径。
