Hello,


First of all, I want to emphasize that I am a beginner with Comsol.

I am trying to import a geometry generated with Matlab into Comsol in order to study the wave propagation in this geometry.

My geometry is simply a n*n matrix, with 2 values : 0 and 1. The value 1 is the material and the value 0 is the air inside the material.

How can I import this matrix into Comsol to work with ?

Thank you for helping out.

Hi Oliver,

I had the same problem as you have and I did onething which I beleive is not the right way but worked. What I did, I visualized the 2D structure in MATLAB using "imagsc" command and then saved the figure as .png file. Then I used an online converter to convert the .png image into the .dxf format which is acceptable by COMSOL.

Hope this helps you,

Good luck,
saeid
