Hi all,
I need to know the way to figure out the available by default output values from different modules which can be used in COMSOL.
To make my statement clear, I am using the magnetic field no current interface and I saw from the code of my senior that he used the value of the field Hx and Hy for calculating magnetic volume force and in the variable section, called these Hx and Hy as mfnc.Hx and mfnc.Hy.
My query is how can I know that Hx and Hy is the output variable from this interface. Where can I see the possible outcomes of a particular module?? Similarly, for heat transfer module, how can I figure out the value of the parameters that I can call further in my code.
Thanks,

Use this forum. Good luck.

Hi Subhasish,
You see the variable or parameter used in the COMSOL model after computing initial results. To do this just right click on the study (Stationary or Time dependent) and compute initial time step. After doing this, In results you can use 1D plot-->global graph--> and the variable you want to use.
Use this variable in --> global definition --> Variable, For further computation.
Hope this helps.
Thanks Ismail...I got it.
So what you want to say is initially I need to set my basic physics by adding the modules and do a basic computation initially by clicking compute and then from results and 1D plot group I can get the default list of variables right??? Is that what you want to say??
Let me try
Thanks for the answer.
Also you can look for the "eye" in the model builder and activate "equation view", once you do that you will find that all the output and intermediate variables are shown under your physics node (e.g. mfnc, solid, etc.)
I got the answer actually. The simplest way is to add a probe. Then if we go to the probe section in the model builder and click replace expression, then we can find all the outputs with shortcut format of calling the parameters at any point in the program according to the added physics tree.
I think my solution offer some advantages, since you can see also the expression of the variable, so you can find how it is calculated by the software, and you don't even need a probe.
