Calypso is a set of codes for magnetohydrodynamics (MHD) dynamo simulation in a rotating spherical shell using spherical harmonics expansion methods.

• Solve MHD equations in a rotating spherical shell
• Treat conductive fluid with Boussinesq approximation
• Inner core can have the same conductivity as that for the fluid core
• Inner core can rotate by viscous torque and Lorentz force
• Support thermal and compositional buoyancies
• Thermal and compositional diffusivity can set independently
• Heterogeneous thermal boundary condition is supported
• Parallelized by MPI and OpenMP
• Visualization output for arbitrary quadric surface (e.g. plane, cylinder, or sphere) and isosurfaces

• Add cross sectioning and isosurfacing module
• Improve Legendre transform
• Parallelization of assemble_sph
• A number of bug fix
• Solve a magnetohydrodynamics (MHD) simulation in a rotating spherical shell.
• Treat Boussinesq fluid with electorical conductivity
