I am working on one composite analysis project in COMSOL multiphysics and i am completely new in this software. 

The problem is, I have one geometrical domain which material is polymer and I have to assign spherical filler particle randomly within this polymer domain. To generate random coordinate of filler particle, I have wrote a MATLAB script. 

Now, I have random coordinates of filler particle from that MATLAB script. The main problem is, how can i import this script into COMSOL so that COMSOL can use that random coordinate and generate a geometry of randomly assign filler particle within the domain.

These random coordinates are within the domain boundary and has verified with overlapping.
