是的，我的系统也是这样，comsol界面始终处于启动状态
在matlab中运行m文件也可以调用comsol（好像是后台调用）

不知道其他用户用的时候是不是也是这样，如果也是，可能就是comsol4开始matlab调用comsol不像以前那样会两者都显式打开

而且按照你引用的文档上说的，在matlab下确实实现了“save the model on file (.mph)",而且这个.mph我们可以用comsol单独打开然后继续建模，这也实现了文档所说的

另外我的系统还有comsol3.5a，所以我安装4后，还有一个comsol with matlab（3.5a兼容模式的菜单），运行这个菜单，可以将3.5a版本的m文件转化为4.0版本的m文件

是安装完后没有出现comsol with matlab的快捷方式吧？
在bin目录下页找不到，安装过程中也没有找到设置matlab路径的地方
查看comsolsetup.log

似乎它自动读取注册表，只找到我装的08b的32位版本的，我还装了个64位的10a版本，并没有检测到
不清楚是什么原因

Optional LiveLink for MATLAB Requirements
The LiveLink for MATLAB is compatible with MATLAB 2009b and MATLAB 2010a.

Changing the Path to the MATLAB Installation
Edit the file [/url]comsolserver.ini and comsol.ini in the bin/<platform> directory under the COMSOL installation directory (typically /Applications/COMSOL40). In the file, change the line
Dcs.mlroot=/Applications/MATLAB_R2010a.app
to point to the root directory of your MATLAB installation

上面两段帮助看了，在comsolserver.ini中也没找到对应行

When I use the "COMSOL with MATLAB" shortcut from the Windows start menu, nothing happens. The target path in the start menu needs to be replaced

不是。有图标。我用2010a。出错（见图）

安装crack都没有问题，好像的确是comsol自己的问题，它不认识我的系统。

那我在xp下试试，我的xp就装了个驱动，方便测试。我先试试看。

haotebaobao · 发表于 2010-5-15 10:04:56

xp-sp3安装了一变。从菜单启动和您一样的错误！

从command line正常。

原因可能是系统缺少组件，如NET Framework （xp下我没装这些）。其他系统没有这个现象。

你是说xp-sp3，命令起动comsol with matlab可以起动？

flyingmind · 发表于 2010-5-15 21:57:21

本帖最后由 flyingmind 于 2010-5-16 07:59 编辑

1. 先运行起动菜单下comsol 4.0->client server->comsol multiphysics 4.0 server

2. 等到出来让输入用户名时：随便输入个你喜欢的
密码输入好后回车，然后重新输入一次（两次要一致,也是随你喜欢输）
然后等到出来成功的消息后就可以关闭这个命令行窗口了
3. 然后起动comsol with matlab菜单就可以了（电脑重启后依然可以）
4. 运行完matlab里程序后，退出matlab后还会出现那个....log的提示框，不过应该不影响使用
5. 不过先打开comsol，然后运行里面的connect to server是不行的，大概是因为没有指定对象吧（比如matlab或者java吧，comsol with matlab的命令是comsol server matlab）

PS：我的系统是win7 x64，matlab2010a x64

不过现在在找通过matlab运行comsol4保存的m文件，还在学习中

haotebaobao · 发表于 2010-5-15 22:54:59

我从命令行可以的。不过从菜单更方便些！

你把命令做成一个批处理文件，放个快捷方式在桌面
点击运行和菜单一样的效果

有时候如果这样设置还是无法启动的话
可能是你还安装了comsol 3.5a
这时，需要重装comsol 4，然后将C盘对应用户目录下的有关comsol的设置删除
在安装上面的方法尝试，应该就可以连上了

尤其注意的是，选择matlab目录时，一定要选到matlabxxxx的根目录下（该目录下有bin等目录），而不是选择到.../bin目录下，这个和以前版本的comsol与matlab连接选择matlab目录是一样的

flyingmind 发表于 2010-5-16 13:39

试了你的方法，但在我这里似乎不行？

1） comsol multiphysics 4.0 server ，输入用户名密码。
2）点击comsol with matlab菜单。matlab倒是启动了，但没有comsol界面。
3）在matlab中运行“comsolserver matlab”，matlab不认识这个命令。

系统为 xp sp3，没有comsol 3.5a等旧版本。

flyingmind · 发表于 2010-5-16 21:56:36

15# TBE_Legend

运行comsol with matlab后，只有一个comsol的启动界面（并没有进去）
然后matlab被启动了，这样就可以了
你可以试着在comsol中将一个例子保存为m文件，然后在matlab中运行了（comsol with matlab），具体使用方法要看livelink to matlab文档了
TBE，你这样已经连接成功了

多谢fly，你说得很对，两者的确是连上了，但desktop of comsol 不出现也的确不正常。

比如那个guide中的例子：

clear; clc
model = ModelUtil.create('Model');
% Create the geometry
model.geom.create('geom1', 2);
model.geom('geom1').feature.create('sq1', 'Square');
model.geom('geom1').run;
% Create the mesh
model.mesh.create('mesh1', 'geom1');
model.mesh('mesh1').feature.create('fre1', 'FreeTri');
model.mesh('mesh1').run;
model.mesh('mesh1')
% Setup physics
es=model.physics.create('es', 'Electrostatics', 'geom1');
es.feature('ccn1').set('epsilonr_mat', 1, 'userdef');
es.feature.create('gnd1', 'Ground', 1);
es.feature('gnd1').selection.set([2]);
es.feature.create('sfcd1', 'SurfaceChargeDensity', 1);
es.feature('sfcd1').selection.set([4]);
es.feature('sfcd1').set('rhoqs', 1, '1e-10');
% Create the study
model.study.create('std1');
model.study('std1').feature.create('stat1', 'Stationary');
model.study('std1').run;
% Create a plot group
model.result.create('pg1', 2);
model.result('pg1').set('data', 'dset1');
model.result('pg1').feature.create('surf1', 'Surface');
mphplot(model,'pg1');
model.save('model1');

复制代码

的确可以正常运行，并在当期工作目录下生成mph文件。但是文档中所说的“You can save the model on file and continue modeling in the COMSOL Desktop.” 不能进行，因为comsol界面始终处于启动状态。

你的系统也是这样的？
