Hi,

I am having trouble in using analytic functions for building geometry in COMSOL 4.4. I would like build an array of circles in x direction and the radius of circle depends on the location of the circle in the array. For this purpose, I defined an analytic function (r(x)). Comsol doesn't allow me to use analytic function in circle's radius definition. Is there something wrong in what I'm doing ? Can you please suggest a way for doing this.

Thanks,
Manoj

Hi,

I coded my geometry in Matlab and linked it with Comsol.

Currently, the only way to use advanced functions is geometries is to use the COMSOL API. Either by writing Java code (e.g. in an app) or by using LiveLink for Matlab or LiveLink for Excel (VBA).

Lest this thread get misinterpreted: You can use a wide variety of functions in parametric curves and parametric surfaces, see e.g. this thread: www.comsol.com/community/forums/general/thread/99891
