最近经常遇到COMSOL用户提出COMSOLV4.0 很多问题以及Bug,其实主要是目前大家安装到网上找到的COMSOLV4.0版本为COMSOL公司内部发布的测试版,而正式对外发布的版本应该为COMSOL 4.0.0.925版本,在测试版以及正式版发布之后,COMSOL公司发布了多次补丁,只是由于非正版用户未能及时收到补丁包,造成了很多时候软件使用问题。建议大家使用COMSOLV4.0a以及以上版本。特别是最近中仿公司免费试用COMSOLV4.1版本。申请地址:http://i.cntech.com.cn/forum/post/show/tid/1142.html
COMSOL 4.0 Update
This cumulative update includes corrected documentation and corrects several bugs in the help functionality and physics interfaces. Update Details.
Installation
Check your version
Make sure that you run COMSOL version 4.0.0.925 or later. On the Help menu, click About COMSOL Multiphysics to check your version. If you have an earlier build number, contact your COMSOL sales representative to get the official release of COMSOL 4.0 before you proceed.
Delete old resources
Windows
Exit any running sessions of COMSOL. Check in the Windows Task Manager and end any COMSOL processes or, alternatively, reboot your computer. Locate your home directory. On Windows XP, this is usually C:\Documents and Settings\[login_name]\. On Windows Vista and 7, it is usually C:\Users\[login_name]\. In your home directory, delete the subdirectory .comsol/v40. Also delete /ver40, if it exists.
Linux
Exit any running sessions of COMSOL. In your home directory, locate the subdirectory .comsol/v40 and delete it. Also delete /ver40 if it exists.
Macintosh
Exit any running sessions of COMSOL. In your home directory, locate the subdirectory Library/Preferences/COMSOL/v40 and delete it. Also delete /ver40 if it exists.
Download Update
[table][tr][td]
Install
Windows
Run the downloaded .exe-file to extract the update to the COMSOL 4.0 installation directory, for example C:\COMSOL40.
Linux
Copy the downloaded .zip-file to the COMSOL 4.0 installation directory:
cp comsol_4.0.0.937_linux.zip [installdir]/comsol40
where [installdir] is the root of the installation, for example /usr/local. Unzip it by the commands:
cd [installdir]/comsol40
unzip -o comsol_4.0.0.937_linux.zip
Macintosh
Double-click the downloaded .dmg file to mount the disk image. In the Finder, open the mounted disk and double-click the COMSOL installer icon.
Check your installation
- Start COMSOL Multiphysics.
- On the Help menu, click About COMSOL Multiphysics.
- Check that the version number is 4.0.0.937 (If not, the installation did not succeed).
Update Details
The periodic updates are cumulative, meaning the latest update contains all previous updates for version 4.0. The contents of each update are listed below.
4.0.0.937, Released May 21 2010
This update adds corrected model documentation and addresses software instabilities when using the Fluid-Structure Interaction (FSI) interface, and when using the difference operation on 3D geometries. The following documentation is updated:
- COMSOL Multiphysics model documentation
- AC/DC Module model documentation
- Acoustics Module model documentation
- Chemical Engineering Module model documentation
- Earth Science Module model documentation
- Heat Transfer Module model documentation
- MEMS Module model documentation
- Structural Mechanics Module model documentation
4.0.0.929, Released May 5, 2010
General Fixes
