A set of concentric spherical shells.
- Note
- This domain will use a spherical harmonic basis in the angular directions. It cannot be used with subcell.
- See also
- Sphere for a spherical domain compatible with subcell
This domain creator offers one grid anchor "Center" at the origin.
Time dependent maps
There are two ways to add time dependent maps to the SphericalShells domain creator. In the input file, these are specified under the TimeDependentMaps: block.
TimeDependence
You can use a simple TimeDependence (e.g. domain::creators::time_dependence::UniformTranslation or domain::creators::time_dependence::RotationAboutZAxis) to add time dependent maps. This method will add the same maps to all blocks in the domain.
Hard-coded time dependent maps
The SphericalShells domain creator also has the option to use some hard coded time dependent maps that may be useful in certain scenarios. This method adds the maps in domain::creators::sphere::TimeDependentMapOptions to the domain. Currently, the first (inner-most) shell has maps between Frame::Grid, Frame::Distorted, and Frame::Inertial while all subsequent shells only have maps between Frame::Grid and Frame::Inertial.
None
To not have any time dependent maps, pass a std::nullopt as the appropriate argument in the constructor. In the input file, simply have TimeDependentMaps: None.
