JustRelax.jl

The JustRelax.jl package exploits the two powerful emerging paradigms in HPC, Massively parallel relaxation-cased solvers and HPC with Julia.

The package is aimed to provide a reusable, extensible and high-performance framework, so that they may be applied within existing application codes and used to develop new ones.

JustRelax contains solvers which are based on the accelerated pseudo-transient (PT) iterative method.

Workflow

The JustRelax.jl package contains the solvers for different geophysical problems modelled using PDEs.

The package is self-contained and is equipped with the boundary conditions and global computational kernels
