Hall of Fame of simulations performed with SLOTH

Coalescence of two bubbles

This simulation is adapted from a case published in L.Bu, et al., Comp. and Math. With Appl. 78(2019)3485–3500.

The initial condition consists of two bubbles that coalesce over time.

This 3D simulation is run with $32$ million DOF over $4096$ MPI processes on Topaze supercomputer at CEA.

Sintering test with nine unequal sized particles (3D)

This simulation is based on a case published in Biner et al., (2017), Springer International Publishing.

Their 2D case has been extended in 3D with more than $4.8$ million DOF. The simulation has been performed with $4096$ MPI processes on Topaze supercomputer at CEA.

Regarding the numerical scheme, Cahn-Hilliard and Allen-Cahn problems are solved using a partitioned algorithm but the Allen-Cahn equations are tightly coupled.

Time evolution of a polycristalline microstructure with 102 grains (2D)

This simulation is based on a case published in Biner et al., (2017), Springer International Publishing.

The polycristalline microstructure is composed of 102 grains (instead of 25 in Biner's book).

Regarding the numerical scheme, Allen-Cahn equations are solved using an implicit monolithic algorithm.

Time evolution of a polycristalline microstructure with 30 grains (2D and 3D)

This simulation is based on a case published in Biner et al., (2017), Springer International Publishing.

The polycristalline microstructure is composed of 30 grains (instead of 25 in Biner's book).

Regarding the numerical scheme, each Allen-Cahn equation is solved using an implicit monolithic algorithm.

This 2D case has been extended in 3D with more than $2$ million DOF. The simulation has been performed with $2048$ MPI processes on Topaze supercomputer at CEA.

Incipient melting in a pellet fragment under an ad-hoc temperature dependent enthalpy of melting

This test has been performed in order to challenge the code over a huge number of degrees of freedom (DOF). Indeed, this 3D simulation is run with $1.2$ billion DOF over $32768$ MPI processes on Topaze supercomputer at CEA

Spinodal Decomposition

This case is based on the work published in J. Shin et al., (2014), App. Math. & Comp. 244, 606-612. Their 2D case has been extended in 3D with more than $132$ million DOF.

The simulation has been performed with $2048$ MPI processes on Topaze supercomputer at CEA.

Manufactured Allen-Cahn Solution

This case is taken from the NIST PFHub repository.

It corresponds to a manufactured Allen-Cahn solution problem.

2D non linear time-dependent diffusion

This case is taken from the MFEM website. It correspond to the example 16 but here extended to an implicit non linear resolution.
