ANSYS_数据文件读写的APDL命令详解及实例
ANSYS_数据⽂件读写的APDL命令详解及实例ANSYS 数据⽂件读写的APDL命令详解及实例作者：huright⼀ FORTRAN数据格式I格式(⼜叫整数格式)⼀般形式：Iw 或：Iw.m其中：w ⼀个数据占的位数宽度（⼜称“字段宽度”），m 需要输出的最少数字位数。
例1：（1）数字在指定的区域内向右端靠齐，如果数字位数⽐指定的字段宽度w⼩，则左边补以空格。
负数的符号也包含在字段宽度内。
（2）如果数字的位数超过了规定的字段宽度w，则不输出有效数据，⽽在该字段宽度范围内充满“*”符号。
（3）如果数字的位数超过了m,则按实际应输出的位数输出（但条件是不能超过w)。
m 不包括负号所占的⼀列。
F格式(⼜叫⼩数型格式)⼀般形式：Fw.dw 各数值占的总位数 d 输出数据的⼩数位数（⼩数点后的位数）。
例1：（1）数字在指定的区域内向右端靠齐，如果数字位数（含⼩数点和符号位）⽐指定的字段宽度w⼩，则左边补以空格；如果数字的位数超过了规定的字段宽度w，则不输出有效数据，⽽在该字段宽度范围内充满“*”符号。
（2）如果数据的⼩数位数⽐指定的⼩数位数d⼩，则在⼩数右边补0以凑⾜d位；如果⼩数位数⼤于d位，则输出时多于的⼩数位数按“四舍五⼊”规则舍去。
（3）假设b为数据整数部分的位数，则应使w≥b+d+1(⼩数点占⼀列），如果输出负数，则应保证w≥b+d+2(⼩数点和负号各占⼀列）。
（4）⽤F格式输出时应注意，由于难以事先确切估计出数据的⼤⼩，输出⼤的数时容易产⽣“宽度不够”的错误（由于w不够⼤），输出⼩的数时会出现丢掉有⽤数字的情况（由于d不够⼤⽽将后⾯的数字截去），这就是“⼤数印错，⼩数印丢”。
E格式(⼜叫指数型格式)⼀般形式：w.dw 各数值占的总位数，d 输出数据的⼩数位数（⼩数点后的位数）。
例1：（1）采取标准化的指数形式输出⼀个实数，d为以指数形式出现的数据的数字部分的⼩数位数。
（2）指数部分⼀般占4列，其中字母“E”和指数的符号各占⼀列，指数2列。
ANSYS经典APDL编程
ANSYS经典APDL编程在使⽤ANSYS的过程中的⼀些经验总结:Ansys Workbench 虽然进⼊UI阶段，但是语⾔命令仍然是其基础核⼼。
1.ANSYS中的⼀些关键概念的理解;参数化程序设计语⾔(APDL) 参数化程序设计语⾔(APDL:ANSYS Parametric Design Language)实质上由类似于FORTRAN77的程序设计语⾔部分和1000多条ANS YS命令组成。
其中,程序设计语⾔部分与其它编程语⾔⼀样,具有参数、数组表达式、函数、流程控制(循环与分⽀)、重复执⾏命令、缩写、宏以及⽤户程序等。
标准的AN SYS程序运⾏是由1000多条命令驱动的,这些命令可以写进程序设计语⾔编写的程序,命令的参数可以赋确定值,也可以通过表达式的结果或参数的⽅式进⾏赋值。
从ANSYS命令的功能上讲,它们分别对应ANSYS分析过程中的定义⼏何模型、划分单元⽹格、材料定义、添加载荷和边界条件、控制和执⾏求解和后处理计算结果等指令。
⽤户可以利⽤程序设计语⾔将ANSYS命令组织起来,编写出参数化的⽤户程序,从⽽实现有限元分析的全过程,即建⽴参数化的CAD模型、参数化的⽹格划分与控制、参数化的材料定义、参数化的载荷和边界条件定义、参数化的分析控制和求解以及参数化的后处理。
宏是具有某种特殊功能的命令组合,实质上是参数化的⽤户⼩程序,可以当作ANSY S的命令处理,可以有输⼊参数或没有输⼊参数。
缩写是某条命令或宏的替代名称,它与被替代命令或宏存在⼀⼀对应的关系,在AN SYS中⼆者是完全等同的,但缩写更符合⽤户习惯,更易于记忆,减少敲击键盘的次数。
ANSYS⼯具条就是⼀个很好的缩写例⼦。
⽤户界⾯设计语⾔(UIDL) 标准ANSYS交互图形界⾯可以驱动ANSYS命令,提供命令的各类输⼊参数接⼝和控制开关,⽤户在图形驱动的级别上进⾏有限元分析,整个过程变得直观轻松。
⽤户图形界⾯设计语⾔(UIDL)就是编写或改造ANSYS图形界⾯的专⽤设计语⾔,主要完成以下三种图形界⾯的设计: 主菜单系统及菜单项对话框和拾取对话框帮助系统通过⽤户界⾯设计语⾔(UIDL),⽤户可以在扩充ANSYS功能的同时建⽴起对应的图形驱动界⾯,如在主菜单的某位置增加菜单项,设计对应的对话框、拾取对话框,实现参数的输⼊和其它程序运⾏的控制,同时提供相应的联机帮助,使操作者能⽅便地获取系统帮助。

使用工具条－工具条嵌套
• 如果有很多按钮，将其放在一个工具条上会显得太拥挤，同时ANSYS也 要求每个工具条不超过100个按钮。——解决办法是工具条嵌套。 工具条嵌套意味着：一个工具条的某个按钮指向的是另一个工具条，而不 是像通常那样指向命令、函数或者宏。 按照这种方式，理论上可以建立无限个缩略词，即产生无限的按钮。 在每个工具条上加上一个RETURN按钮，以返回上一级工具条（好习惯 ）。

字符参量
• 字符参量代表不超过8个字符的字符串，字符参量的定义、修改和删除与标量参 量的基本一致。 Remember：定义字符参量时用单引号（‘’）括起来。 字符参量的典型用法是提供文件名及其扩展名。
• •
• 用法： 1、当某个命令需要输入字符时，可以用字符参量代替：如调用宏 NAME=‘MyMACRO’ ABC=‘SX’ *USE,NAME,ABC 或 *USE,NAME,’SX’ 2、判断： EF=‘NO’ *IF,EF,NE,’YES’,THENDec,2 Nhomakorabea2004

利用ANSYS内嵌的函数进行赋值
•
对于某些参量，可以利用内嵌函数来代替*GET命令。内嵌函数返回参量的 值并直接用于当前的计算中。这样做就不必先赋值给参量，而在运行中直接 调用该参量，省去了中间参量。 如：计算两个结点的中点的位置，如果采用*GET命令，则需输入： *GET,L1,NODE,1,LOC,X *GET,L2,NODE,2,LOC,X MID=(L1+L2)/2 而用内嵌函数时则变得很简单： MID=(NX(1)+NX(2))/2
