    "abstract": "A new numerical finite difference code has been developed to solve a thermal\nconvection of a Boussinesq fluid with infinite Prandtl number in a\nthree-dimensional spherical shell. A kind of the overset (Chimera) grid named\n``Yin-Yang grid\u0027\u0027 is used for the spatial discretization. The grid naturally\navoids the pole problems which are inevitable in the latitude-longitude grids.\nThe code is applied to numerical simulations of mantle convection with uniform\nand variable viscosity. The validity of the Yin-Yang grid for the mantle\nconvection simulation is confirmed.",
