Rayleigh

Rayleigh is a 3-D convection code designed for the study of dynamo behavior in spherical shell geometry. It evolves the incompressible and anelastic MHD equations in spherical geometry using a pseudo-spectral approach.

Rayleigh employs spherical harmonics in the horizontal direction and Chebyshev polynomials in the radial direction. The code has undergone extensive accuracy testing using the Christensen et al. (2001) Boussinesq benchmarks and the Jones et al. (2011) anelastic benchmarks. Rayleigh has been developed with NSF support through the Computational Infrastructure for Geodynamics (CIG).

Current Release

Source Packages

Rayleigh-0.9.1.tar.gz [2018-04-28]

This release fixes a number of bugs that could cause crashes at output time.

  1. Several output-quantity codes were double-booked. This could cause issues with quantity codes in the following ranges:
    • 1900--2000 (kinetic energy equation codes)
    • 1400--1600 (thermal energy equation codes)
    • 1600--1800 (magnetic energy equation codes)
    The output quantity tables have been adjust accordingly.

  2. Logical errors affecting outputs involving v' dot grad v' have been corrected.

  3. The configure script now accepts the --with-custom and -devel flags (run ./configure --help for details)
