A spherical compression about some center, as given by domain::CoordinateMaps::TimeDependent::SphericalCompression<false>.
Details
This TimeDependence is suitable for use on a spherical shell, where MinRadius and MaxRadius are the inner and outer radii of the shell, respectively.
- Note
- The quantity stored in the FunctionOfTime is really the spherical-harmonic coefficient \(\lambda_{00}(t)\). This is different from the Shape map, which stores ylm::Spherepack coefficients \(a_{lm}(t)\) and \(b_{lm}(t)\) instead of \(\lambda_{lm}(t)\). See domain::CoordinateMaps::TimeDependent::Shape for more details.
