Capacitance Matrix of Two Spheres
Application ID: 49751
This model compares the numerical and analytical solutions for the capacitance matrix of two non-concentric spheres. It also illustrates the relation between the Maxwell capacitance matrix and the mutual capacitance matrix.

This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- CAD Import Module and
- either the AC/DC Module, MEMS Module, or Plasma Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
