Hello everyone, how's it going?

I would like to know how to construct a 3D geometry of a cylinder containing spheres formed into a tetrahedral shape. The height of the cylinder is 2 meters, with 50 mm diameters filled with 1 mm spheres up to approximately 1 m. Is there a way to do this in comsol?

Thanks.

Hello Gabriel,

You could write a model method to achieve this. See this blog for a starting point. Another approach, if you have LiveLink for MATLAB on your license, is to use that to script your geometry.

Best,

Jeff

PS: Beware that you're talking about a lot of spheres in that cylinder, so that the model will be very large. Depending on what you are trying to get out of the simulation, other approaches than representing each sphere explicitly may be more appropriate (e.g. using effective properties in the region where the spheres are).
