hi,
how to convert comsol plots into matlab plots? i am using comsol v 4.1 earlier i was using v3.4 in which i could easily get the cordinates of the plot, but i am not able to find that option in V4.1

Hi,
this requires, that you connect Matlab to the Comsol server.
In linux it would be the command "comsol matlab server".
Alternatively you can also start Matlab first, then add the path <dir>/COMSOL41/mli (where <dir> is the architecture root directory).
Here is a list of commands, which you should execute in Matlab/Comsol:
In Matlab:
1. addpath <dir>/COMSOL41/mli
2. mphstart
3. import com.comsol.model.*
4. import com.comsol.model.util.*
Then in Comsol "File -> Export Model to Server" and give your model a NAME
Back in Matlab: model = ModelUtil.model('NAME');
Now the model is in your workspace.
With the command mphplot (check the documentation on this for the syntax and options) you can access any plot group of your comsol model and create a matlab plot.
There are some other useful commands that start with "mph" that might be of interest for you.
Hope this helps,
Juergen

hi
I tried your solution but I got an error as below:
Undefined variable "ModelUtil" or class "ModelUtil.model".

Hi
In recent versions of Comsol you can simply do
pd = mphplot(model, 'pg1');
and then pd is a struct variable that contains all the necessary settings for recreating the plot in Matlab.
Note that this requires LiveLink for Matlab.
