ASPECT - Advanced Solver for Problems in Earth's ConvecTion

License GPL2+: Online Documentation DOI pdf manual


ASPECT is a code to simulate convection in Earth's mantle and elsewhere. It has grown from a pure mantle-convection code into a tool for many geodynamic applications including applications for inner core convection, lithospheric scale deformation, two-phase flow, and numerical methods development. The project is supported by CIG (

Installation instructions

The steps to install the necessary dependencies and ASPECT itself are described in the Installation instructions section of the ASPECT manual.
