(完整版)ANSYS最常用命令流+中文注释(超级大全)ANSYS最常用命令流+中文注释VSBV, NV1, NV2, SEPO, KEEP1, KEEP2 —Subtracts volumes from volumes,用于2个solid相减操作,最终目的是要nv1-nv2=?通过后面的参数设置,可以得到很多种情况:sepo项是2个体的边界情况,当缺省的时候,是表示2个体相减后,其边界是公用的,当为sepo的时候,表示相减后,2个体有各自的独立边界。
keep1与keep2是询问相减后,保留哪个体?当第一个为keep时,保留nv1,都缺省的时候,操作结果最终只有一个体,比如:vsbv,1,2,sepo,,keep,表示执行1-2的操作,结果是保留体2,体1被删除,还有一个1-2的结果体,现在一共是2个体(即1-2与2),且都各自有自己的边界。
如vsbv,1,2,,keep,,则为1-2后,剩下体1和体1-2,且2个体在边界处公用。

substep: 指定从哪个子步开始继续分析。缺省为本目录
此命令由已知的一组直线(L1,…L10)围绕成面(Area), 中,runn 文件中最高的子步数
至少须要 3 条线才能形成面,线段的号码没有严格的顺序限制,
action, continue: 继续分析指定的 ldstep,substep
只要它们能完成封闭的面积即可。
复制命令。itime 包含本身所复制的次数;na1,na2,ninc 为现有 TANH(X) 双曲正切
的坐标系统下复制到其他位置(dx,dy,dz);kinc 为每次复制时面 17、antype, status, ldstep, substep, action
积号码的增加量。
声明分析类型,即欲进行哪种分析,系统默认为静力学分析。

(完整版)ANSYS命令流总结(全)
ANSYS结构分析单元功能与特性/可以组成一一些命令,一般是一种总体命令(session),三十也有特殊,比如是处理/POST1! 是注释说明符号,,与其他软件的说明是一样的,ansys不作为命令读取,* 此符号一般是APDL的标识符,也就是ansys的参数化语言,如*do ,,,*enddo等等NSEL的意思是node select,即选择节点。
s就是select,选择。
DIM是定义数组的意思。
array 数组。
MP命令用来定义材料参数。
K是建立关键点命令。
K,关键点编号,x坐标,y坐标,z坐标。
K, NPT, X, Y, Z是定义关键点,K是命令,NPT是关键点编号,XYZ是坐标。
NUMMRG, keypoint 用这个命令,要保证关键点的位置完全一样,只是关键点号不一样的才行。
这个命令对于重复的线面都可以用。
这个很简单,压缩关键。
Ngen 复制节点e,节点号码:这个命令式通过节点来形成单元NUMCMP,ALL:压缩所有编号,这样你所有的线都会按次序重新编号~你要是需要固定的线固定的标号NSUBST,100,500,50:通过指定子步数来设置载荷步的子步LNSRCH线性搜索是求解非线性代数方程组的一种技巧,此法会在一段区间内,以一定的步长逐步搜索根,相比常用的牛顿迭代法所要耗费的计算量大得多,但它可以避免在一些情况下牛顿迭代法出现的跳跃现象。
LNSRCH激活线性搜索PRED 激活自由度求解预测NEQIT指定一个荷载步中的最大子步数AUTOTS 自动求解控制打开自动时间步长.KBC -指定阶段状或者用跳板装载里面一个负荷步骤。

(完整版)ANSYS命令流总结(全)
ANSYS结构解析单元功能与特征/POST1/可以构成一一些命令,一般是一种整体命令( session),三十也有特别,比方是办理 ! 是说明说明符号,,与其余软件的说明是相同的, ansys 不作为命令读取,*此符号一般是 APDL 的表记符,也就是 ansys 的参数化语言,如 *do ,,,*enddo 等等NSEL 的意思是node select,即选择节点。
s 就是 select,选择。
DIM是定义数组的意思。
array 数组。
MP 命令用来定义资料参数。
K 是建立要点点命令。
K, 要点点编号 ,x 坐标 ,y 坐标, z 坐标。
K, NPT, X, Y , Z 是定义要点点, K 是命令, NPT 是要点点编号, XYZ 是坐标。
NUMMRG , keypoint 用这个命令,要保证要点点的地点完整相同,不过要点点号不一样样的才行。
这个命令关于重复的线面都可以用。
这个很简单,压缩要点。
Ngen 复制节点e,节点号码:这个命令式经过节点来形成单元NUMCMP,ALL :压缩所有编号,这样你所有的线都会挨次次重新编号 ~你若是需要固定的线固定的标号NSUBST,100,500,50 :经过指定子步数来设置载荷步的子步LNSRCH 线性搜寻是求解非线性代数方程组的一种技巧,此法会在一段区间内,以必定的步长逐渐搜寻根,对比常用的牛顿迭代法所要耗费的计算量大得多,但它可以防备在一些状况下牛顿迭代法出现的跳跃现象。

ansys桥梁受力分析命令流
ANSYS桥梁受力分析命令流ANSYS是一款广泛应用于工程领域的有限元分析软件,它可以帮助工程师、设计师、科学家等进行各种力学或结构分析。
在工程领域中,桥梁是一种比较常见的结构,因此本文将介绍在ANSYS中进行桥梁受力分析的命令流。
1. 建立桥梁模型首先,我们需要建立桥梁模型。
在ANSYS中,可以使用多种模型建立工具,例如现在比较流行的三维CAD软件,如SolidWorks、CATIA等,均可以建立出桥梁模型。
建立好桥梁模型后,需要导入到ANSYS中进行后续分析。
2. 分配材料属性桥梁模型建立完后,需要根据实际情况为它分配材料属性。
以混凝土桥梁为例,我们可以使用“MP(材料属性)”命令为桥梁定义混凝土的相应属性。
比如,定义混凝土的弹性模量、泊松比等。
3. 设定支座约束桥梁的受力分析需要考虑桥梁的支座约束情况。
在ANSYS中,我们可以通过使用“SUPPORT”命令设定不同类型的支座约束。
4. 设定荷载桥梁承受的荷载对于力学分析至关重要,因此在进行桥梁受力分析时,必须设定荷载的种类和大小。
ANSYS提供了多种荷载设定方式,如集中荷载、分布荷载、自重荷载等。
5. 载荷应用载荷应用是桥梁受力分析中的一个关键步骤,它能够准确模拟桥梁所受荷载。
在ANSYS中,可以使用“D”命令定义荷载的应用方式,如定义一个位移荷载、力荷载等。
6. 求解过程ANSYS中提供了多种求解器,可以快速准确地解析桥梁模型受力情况。
在进行桥梁受力分析时,需要选择合适的求解器并进行计算。
ANSYS中提供了两种类型求解器,一种是基于传统矩阵进行计算的Direct Solver求解器,另一种是基于有限元模型优化的Iterative Solver求解器。
7. 结果分析在桥梁受力分析计算完成后,需要对应力和位移等结果进行分析并产生可视化的输出。
在ANSYS中,可以使用“POST1”命令来输出结果,并对结果进行后处理。
8.经过以上步骤进行受力分析后,可以得到桥梁受力的详细情况,也可以对桥梁的结构进行合理的优化。

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。
9、*AFUN,Lab在参数表达式中,为角度函数指定单位.Lab:指定将要使用的角度单位.有3个选项.RAD:在角度函数的输入与输出中使用弧度单位(默认)DEG:在角度函数的输入与输出中使用度单位.STAT:显示该命令当前的设置(即是度还是弧度).10、Agen, itime,na1,na2,ninc,dx,dy,dz,kinc,noelem,imove !面积复制命令。
