InterfaceType

Type:enum Range:CrossSection, DomainInterfaces, ExteriorDomain, InteriorExterior Default:-/- Appearance:simple

Selects the type of interfaces. In the following, cylindrical problems with a cross-section computational domain are treated using the same syntax as for the corresponding 3D problem.

• DomainInterfaces

  Selects the interfaces between neighboring physical domains as specified in the layout file (Layout, DomainId). For two-dimensional problems the interfaces are infinite in z-direction.

• CrossSection

  Only allowed for two-dimensional problems with an infinite z-direction. The interfaces are the cross-sections of the physical domains as specified in the layout with normal in -direction. In the output file, the first two columns, DomainIdFirst and DomainIdSecond, are replaced by one column named DomainId.

• ExteriorDomain

  This is specially devoted for scattering problems. Only the scattered field is used in the integrand expression.

  The boundary between the computational domain and exterior domain serves as the interface. In the output table, the first column DomainIdFirst corresponds to the interior and DomainIdSecond to the exterior physical domain. In this case the integers DomainIdFirst and DomainIdSecond may coincide.

• InteriorExterior

  Similar to ExteriorDomain, but now the fluxes of the total field are computed across interior-exterior interfaces.
