DC Card
Domain connectivity (discontinuous Galerkin domain decomposition method) can be used to connect a discontinuous mesh and geometry where one is a static mesh (for example, a large imported car model) and the second is dynamic parameterized geometry (for example, a small antenna).
On the Solve/Run tab, in the Solution
settings group, click the Domain connectivity
(DC) icon.

Parameters:
- Number of connections
- Specify the number of connections for the two meshes.
- Label of first/second face
- Define for each connection, the labels of the corresponding faces.
- Tolerance
- Define for each connection point, a tolerance distance to distinguish between regions, where a gap in the model is desired (or not desired).
Requirements for Domain Connectivity
The following boundary conditions for the application of the method have to be considered:
- Gap distance g should be about λ/1000 and must not be greater than λ/100.
- The meshes may not penetrate each other.
- The domain connectivity edges may not be part of a dielectric region. However, dielectrics can be defined elsewhere in the model.
- For T-junctions the domain connectivity-cut may not be through the junction.
- Domain connectivity can be applied for MoM and MLFMM, but not for asymptotic methods like PO, LE-PO, RL-GO and UTD.
