Parallel phase-field code for coarsening

This code implements Nele Moelans' phase-field model:

Moelans, N. "A quantitative and thermodynamically consistent phase-field interpolation function for multi-phase systems," Acta Materialia, 59, (2011) p.p. 1077-1086. doi: 10.1016/j.actamat.2010.10.038

This code is used in the work to fit the liquid diffusivity:

Requirement

This code requires the OpenMPI library and the HDF5 library.

Compile and run the code

Compile the code:

icc -O2 -o ppf -L{dir of hdf5 library} -L{dir of mpi library} -lmpi -lhdf5 phasefield.c

If you run the code on the same machine where it is compiled, add the compiler flag -xhost to enable more optimization.

Run the code:

mpirun -np N ./ppf filename

N - number of cores used

filename - the input file name

Input file

You can generate the input hdf5 file using the following MATLAB code:

etaS = ; etaL = ; c =; s = size(etaS);
h5create(filename,'/etaS',s,'Datatype','double');
h5create(filename,'/etaL',s,'Datatype','double');
h5create(filename,'/c',s,'Datatype','double');
h5write(filename,'/etaS',etaS);
h5write(filename,'/etaL',etaL);
h5write(filename,'/c',c);
