脑里有盗版的ANSYS,我不大肯定能否用这个盗版的license给公司做consulting work.
老板问了一下我的license到底是不是合法的，我暂时还没有给他具体的答案，只是说
这个是学生软件，暂时还可以用。
大家说说看，我如果用这个盗版的license给公司做consulting work的话，会有哪些严
重的后果。
BTW,这个公司不会用我做的work publish any papers. |

发帖数: 138 | 9 我用system命令在ANSI C主程序A中调用另一程序B，
程序B的结果是一个数值，我想把这个结果赋值给程序A中的
一个变量，应该怎么传递呢？
我以前让B把结果写在硬盘上，再在A里把它读出来，感觉很傻。
google了一下，好像是用fork(),execl(),pipe()等等.......

missing, such as stdio.h, strings.h, stdlib.h, etc. Anybody here
had the experiences of IRIX knows which subsystem contains these
files? Without these files, the compilter cannot work and I even
cannot build a hello world. :( |

标 题: ANSI C 问题: 如何找到绝对路径？

比如说，我现在有下列路径情况：

../../test/a.out
在已知的current working dir情况下(e.g. /home/users/xt)

我现在有一个double float

我需要把这个变量code的二进制形式或者八进制或者十六进制输出
我想问得是是要用printf函数吗？还是别的函数？
如果是用printf,使我下面的这个式子吗？
printf("\nThe code in Hex is %#ox\n\n",code);
关键是那个小数很长
我需要他的全部长度
不仅仅他的开头的部分

发帖数: 59 | 15 问题：有一个圆环，被弹簧悬挂在位于圆环圆心的固定点上。在圆环上施加扭矩，要计算
悬挂弹簧的扭转刚度（非线性弹簧）。
用Ansys建模时使用的是实体命令，划分网格使用SOLID95单元（单元本身没有旋转自由度
）。从分析结果中只能读出每一个节点的位移ux,uy,uz。有什么办法可以直接读出圆环在
扭矩作用下整体的旋转角度？

发帖数: 8 | 17 我现在要做一个结构的时程分析，材料是非线性的。材料的应力跟位移和速度都有关系，
也就是说，如果用公式表示的话：材料的应力=f(位移）+g(速度）。f 和g的表达式是已
知的。我的问题是：在Ansys里，怎样建立材料模型。非常感谢!! |

发帖数: 2 | 18 用ansys进行非线性(材料)模拟分析时，一般是假定一个非线性的应力应变关系，也就是

应力(或应变)状态的不同而改变。 |

发帖数: 2433 | 28 I haven't use Ansys for 10 years, don't know how it works anymore. Basicly
you need to use the static electrical solver, define two current boundary
conditions,one in, one out, with same amount of current, and solve for the
current distribution. Voltage condition works the same. You can plot your
current distribution as heat distribution, they are the same. |

如果modeling domain有很多subdomains，如何在post processing的时候，仅仅导出指定

能让Ansys直接输出呢？
用element table什么的会把属于A1的element solution也输出来，混在一起很麻烦。

发帖数: 98 | 47 I met a problem when I used ANSYS to model a composite piezoelectric plate
. I assigned 4 DOF (ux,uy,uz,volt) to all nodes of the two-layer plate(both
layers are made of piezoelectric materials). And the plate are simply
supported at four edges and voltage is applied on the top surface.
During the solving process, error was shown: "specified constraint not
allowed on slave DOF in coupled set". It sounds that Volt DOF are slave DOF.
Why did I encounter this problem when I specify mechanic |
