Building a list of geometrical objects

Hello,

I would like to build a large number of identical geometrical objects (>100 circles of same size and material) inside a 2D box. I have a text file listing the x,y coordinates I want to use, but I don't know of any way of communicating this list to COMSOL. Manually inputting the information by creating new circles is obviously time consuming. Any help would be appreciated.

Thanks.

An indirect way is possible: Draw the geometries in Matlab, and link COMSOL with Matlab. Or equivalently you can save model as .m file and write a loop there.

Use an array. Screen capture attached.

Hello,

Thanks for the response; however, I need to build a list of circles in specific locations. The circles will not be in an ordered array, but rather distributed in "random" locations. I may need to use MATLAB, but I was unaware if COMSOL can directly import a list of x,y coordinates and use those to define circle locations.

Cheers

Thanks for the response. My MATLAB skills are a little rusty (but I do work with some people much more knowledgable than myself), so I'll see what I can do.

Hi Chris,
I am also interested in this topic, did you figure out how to do it? Thank you.
