abaqus 破解方法

from http://www.verycd.com/topics/2832420/ 1. 双击dvd2中的setup.exe，几秒钟后弹出安装对话框，安装documents 2. 把dvd1\crack里面的License文件abq6101.dat拷出来放到硬盘目录下，编辑License文件，this host替换为自己的计算机名（不要改动物理地址和端口），添加ABAQUSLM文件的路径：比如我的 SERVER this_host ID=20111111 27011 VENDOR ABAQUSLM 改为 SERVER dundas ID=20111111 27011 VENDOR ABAQUSLM C:\Abaqus\License\ABAQUSLM.exe 3. 设置系统环境变量我的电脑->属性->高级->环境变量系统变量栏新建变量名: LM_LICENSE_FILE 变量值: 27011@this_host--(this_host为自己的计算机名) 4. 双击dvd1中setup.exe，几秒钟后弹出安装对话框提示安装c++（见后面说明），完成后提示安装license，选择just install the licenseing utilities。 license安装完成后提示安装product,选cancel退出安装。 5. 将编辑后的License文件abq6101.dat复制到安装目录C:\SIMULIA\License下，并新建文件abq6101.log。运行License管理器，建立许可证。具体操作：双击C:\SIMULIA\License目录下的lmtools.exe，选择config services选项卡： Path to lmgrd.exe file指向C:\SIMULIA\License\lmgrd.exe Path to license file指向C:\SIMULIA\License\abq6101.dat Path to debug log file 指向C:\SIMULIA\License\abq6101.log 并勾选：Use Services和Start Server at Power Up，点击Save service" 接着选择Start/Stop/Reread选项卡，点击Start Server，提示Server Start Successful。 6.安装product 双击dvd1中setup.exe选择product，填入激活服务器地址: 27011@this_host(this_host为自己的计算机名)完成安装。双击dvd1中setup.exe会再次弹出安装c++界面，可以跳过此界面直接进入光盘中product文件夹中安装。例如32位系统安装路径：dvd1 H:\win86_32\product\Windows\Disk1\InstData\VM\ 双击install.exe直接安装product。 ---------------------------- 说明双击dvd1中setup.exe，几秒钟后弹出安装对话框提示安装c++等运行环境，安装版本按默认安装，非高级用户不用安装Fortran等运行环境。如果高级用户需要确定会用到abaqus所有运行环境如Fortran等的具体版本，请如下操作：开始->运行 cmd 在命令窗口输入 H:\setup.exe -sysinfo （其中盘符H根据个人情况不同）几秒后出现system requirement status 其中status：pass项为你已经安装的运行环境，fail项为你未安装的运行环境。未安装的运行环境的作用高级用户应该都很清楚了吧

CFD and adina

Today finally understand clear about CFD how it works. there is actually not such thing call pressure-pressure condition, it sounds i am too silly, as there is a redundant condition, you speficy the velocity condition, at the same time, you are also manage to settle the pressure , as in cfd, both side are equalized. one you give magnitdue, another one it will automatically calculate for you. i finally can go into CFD. i also manage to solve adina problem 给版主做个补充：overlap不单指流场网格和结构场发生重叠。由于adina在FSI求解时，采用的是ALE列式，简单些说即流场和结构场交接区域的网格是可变形的，当发生“强耦合”运动时，或者网格初始质量不太好（比如网格的初始夹角太小、塌陷率过大等），一旦网格运动，很容易导致网格变形后出现“雅克比阈值”接近0甚至小于0，产生overlap。各个CFD程序内置的overlap标准也不同，原因在于网格出现压缩或者拉伸后回直接影响积分精度，因此，理论上，这个阈值设置高一些，精度保证就高一些，但出现overlap的概率就大一些。要解决overlap，根本上只能从网格初始质量寻求解决办法。当然，adina内置的一些辅助措施，如设置leader follower对于缓减overlap也是很有效的，甚至有些时候会让“貌似不可算”（主要指初始网格质量很差，能保证开算，但很容易就overlap的模型）的网格顺利计算完毕。有兴趣的可以试试看，在稳态流场计算时，只要模型初始网格雅克比阈值大于0，是不会遇到overlap的，原因在于稳态流场中一般用纯欧拉格式的有限体积法，网格是不会变形的，差别只是收敛时间的长短或者难易。简单些说，雅克比矩阵就是一个多维函数在某点位置对应的各个维度上的偏导数矩阵（该导数矩阵使得改点对应母函数具有线性最优逼近特征），如果偏导数矩阵小于0 ，表示函数在改点存在反向，否则保持原有方向。对于一个单元来说，如果在节点位置出现反向则意味着什么呢？你可以思考一下，再进一步，对一维网格、二维网格、三维网格分别意味着什么呢 http://www.forumadina.com/forum.php?mod=viewthread&tid=209&extra=page%3D1 http://forumadina.com/forum.php?mod=viewthread&tid=274&highlight overlapp的判断标准问题

Pay Monthly Car Installment Using Public Bank
Since I’ve had my bad experience with Maybank, so i won’t use it for my online banking. Currently, my most favor online banking is Public Bank as i found a lot convenient and lower charges than Maybank. For your information, I pay my monthly car installment using Pbebank since it’s more hassle free and save me some travel expenses as i no need to travel to any Public bank branch to make payment.
Step By Step: How To Make Car Installment Using PbeBank?
Step 1: Go to Payment/Recharge -> Loan/Financing Payment -> To Open 3rd Party Accounts

Step 2: Click “Request PAC” button.

Step 3: Key in your PAC now.
Step 4: Select your Public bank saving account to make payment.

Step 5: Key in your beneficiary account number and note number which you can check from any branch of Public Bank by presenting your identity card.
Step 6: Key in your monthly car installment amount. Then, click next. At the end of the payment, you can try to store the registration of your loan/financing accounts so that next time you no need to skip the request PAC number step.

how to set time function in adina

I finally see through adina.

http://www.baisi.net/thread-668630-1-1.html

adina

1.首先获得ADINA8.4版本安装程序，点击..\win32\setup.exe进行开始安装；

2.在安装过程中，当出现选择“license type”窗口时，选择

'floating-industry'作为license管理的类型.；

3.当出现指定服务器地址窗口时，输入 “localhost” 并确认，关闭窗口继续安装到结束。

4.重启动机器。
5.将Crack内的文件lsapiw32.dll替换..\ADINA85\Sentinel和..\ADINA85\x32的同名文件。

i decide to use fortran to write cfd code today.

comsol finding

just realize maybe sometime i am wrong.

why cfd must always have pressure

Today after half a year running, i finally admit my mistake and decide to give myself a restart. as in cfd to stabilize the equation, you must have a

dP without a velocity or mass flow Direchlet constraint is not well-posed. This can be proven mathematically by examining the eigenvalues of the Jacobian matrix of partial derivatives wrt state variables.

You can specify velocity at inlet or outlet and pressure must be specified at the outlet in order to get a well-posed boundary conditions. That is why the boundaries are set up the way they are in COMSOL. They do it correctly, and what you are getting is expected.

** ERROR *** CODE ADF2701: Fluid node (label) 2806 is not attached to solid fluid-structure interface 1. The relative distance to solid boundary element 8382 is 1.49E 01.

1 hellend112 你定义的结构与流场的单元不匹配，可能是两种网格尺寸差距太大，调剂网格 2010/4/24 02:08
2 hellyeah88g0 首先感谢楼上，我做的过程中，两种网格划分是完整一样的阿 2010/4/24 16:48
3 longbn 可能是耦合盘算时，节点自己运动，偏离FSI接触面，我曾遇到这样的问题 2010/4/25 07:27

5 steven 我已经解决了，在MESHING-CREATEPOINT那里输入流固接触点的点号，在MESHING-ALE MESH CONSTRAINTS-FIX MESH 看你所选中的点是否被固定这样在重新画网格就可以了！ 2010/4/26 12:46

7 nxd11g23 因为流体和结构的交互面处的网格不对齐。中间有空隙。处理措施：1.查找空隙的处所，细化网格，或者采用同样的划分方法，避免涌现。2.重新构建此处的流固耦合面。必需要匹配3.如果留空隙，就无法算出结构
