<h1>Open Framework for Testing Optimized Schwarz Methods for Time-Harmonic Wave Problems</h1>
<p>
GetDDM combines <a href="http://getdp.info">GetDP</a>
and <a href="http://gmsh.info">Gmsh</a> to solve large scale finite element
problems using optimized Schwarz domain decomposition methods.
</p>
<h2>Quick start</h2>
<ol>
<li>Download the <a href="http://onelab.info">precompiled ONELAB software
bundle</a> for Windows, Linux or MacOS.
<li>Launch the app <img src="http://geuz.org/gmsh/gallery/icon.png" height=20px>
<li>Open <code>models/GetDDM/main.pro</code>
<li>Press <code>Run</code>
</ol>
<h2>Parallel computations</h2>
<ol>
<li>Download the <a href="http://onelab.info/files/onelab-source.zip">ONELAB
source code</a>
<li>Follow the <a href="">instructions to compile GetDP and Gmsh</a> with MPI
support
<li>The commands for running GetDDM in parallel will depend on your particular
MPI setup. Usually the procedure looks something like this on 100 CPUs:
<pre>
mpirun -np 100 gmsh file.geo -
mpirun -np 100 getdp file.pro -solve DDM
</pre>
Sample scripts for SLURM and PBS schedulers are also available.
