This repository contains demos and example solvers that make use of the MUI Multiscale Universal Interface to perform multiscale/multiphysics computations. The MUI primary repository can be found at https://github.com/MxUI/MUI.

The source code is dual-licensed under both GPL v3 and Apache v2.

To run the examples you need a mpic++ wrapper with C++11 enabled backend.

To run the first example 0-hello-world:

# clone the repository
cd <repository_directory>
git submodule update --init  # to obtain MUI
cd 0-hello-world
make
mpirun -np 1 ./hello mpi://domain1/ifs 0.618 : -np 1 ./hello mpi://domain2/ifs 1.414

To run 2-heat:

cd <repository_directory>/1-heat
make
mpirun -np 1 ./heat-coarse : -np 1 ./heat-fine
matlab -r vizmulti

You can view the time evolution of the simulation by running the vizmulti.m MATLAB script and dragging the slider bar in the figure.

To run 4-bd-ns:

cd <repository_directory>/4-bd-ns
make
mpirun -np 1 ./brownian : -np 4 ./vortex
gnuplot -p plot.gp

Also checkout flow.png for a visualization of the flow field.

To run 5-multi-domain:

cd <repository_directory>/5-multi-domain
make
