Hi:
I have a rectangular structure in Comsol and the field is located in the middle of the domain. I want to export only the data at the middle of the domain where the field is located, can I do that in Comsol? or it has to be done through Comsol script?. I used to do post processing manually and select a regular grid directly from Comsol.
Can anyone help me out with this?, I really need to find a way to export as many points from the middle of the domain as possible.
thanks,
Naema

You can export data from a customized region. In export options you can specify it. I never tried myself, so I don't know if it will be awkward or not. Good luck!

thanks Pu, the problem is that I searched a lot in the options and could not figure it out, do I need to save the mph file as a Matlab file in order to do such a trick!.
I hope someone can guide me on how to do this,
thanks,
Naema

I think you can use a coordinate file to specify the region only within COMSOL.
