Optimization using Simulink similar to solver addon- in MS excel?

I wish to simulate the loci of point at a fixed distance from 2 fixed points in 3-D space in Simulink.

Lets say

A= [x0 y0 z0] %fixed B= [x1 y1 z1] %fixed C= [x y z] % the moving point.

I had used solver add-on to solve it in MS-Excel, ( by using distance constraints and optimizing the distances)

I would like to replicate a similar approach in Simulink. Is there an inbuilt optimizer in Simulink or do I use very high values for controller function?
