abaqus 6.13对操作系统的新要求：
自abaqus 6.13版本开始，将不再支持windows 的32位操作平台；
同时，也不再支持windows xp和windows vista操作系统；
安装：
1. Run "Install Abagus Product & Licensing"
2. In SIMULIA FLEXnet License Server window select "Just install the license utilities"
NOTE: If you already have SIMULIA FLEXnet License Server for ABAQUS 6.12-3 installed and running you can use it for 6.13-1 too
3. After finishing License Utilities setup copy files "ABAQUS.lic" and "ABAQUS.log" to <SIMULIA FLEXnet License Server progdir> (by default C:\SIMULIA\License\)
4. Configure and run SIMULIA FLEXnet License Server as service
4.1. Run lmtools.exe
4.2. On "Servise/License File" tab select "Configuration using Services"
4.3. On "Config Service" tab input the new Service Name (for example: SIMULIA FLEXnet License Server)
4.4. Browse to "lmgrd.exe", "ABAQUS.lic" and "ABAQUS.log" files
4.5. Select "Use Service" and "Start Server at Power Up", click "Save Service"
4.6. On "Start/Stop/ReRead" tab click "Start Server"
4.7. Close lmtools
do not pay attention warning the license file you have selected is not valid for this machine? continue
5. For ABAQUS "Installation type" window select "SIMULIA FLEXnet License Server"
6. In "License Server" window input for "License server1 (REQUIRED)"
27011@<computername>
there <computername> mast be the name of computer with SIMULIA FLEXnet License Server server installed
7. Continue and finish setup
8. Enjoy
简单翻译一下：
1.运行setup.exe，在安装服务器窗口选择"Just install the license utilities"，安装好后先不要点”安装产品“窗口的下一步，先配置lmtools.exe；
2.复制文件"ABAQUS.lic" and "ABAQUS.log"到安装目录（默认是C:\SIMULIA\License\）；
3.运行lmtools.exe，在"Configuration using Services"页选择三个文件"lmgrd.exe", "ABAQUS.lic" 和"ABAQUS.log"，勾选"Use Service" 和"Start Server at Power Up", 点击"Save Service"保存，切换至"Start/Stop/ReRead"页点击"Start Server"，可以看到成功运行，可以关闭本窗口了；
4.返回第一步窗口继续安装产品，在"License Server" 窗口填写27011@<计算机名>，例如我的就是27011@Gao-PC，（6.12版本的用27000@127.0.0.1）
5.成功，很简单吧
注意：网上很多教程说要修改ABAQUS.lic文件第一行并且添加环境变量，完全没有必要，从abaqus6.10到6.13都可以按照本文步骤安装（只有License Server不同），其他版本未测试过。
