====== Delft3D Installation and Simulation on LENGAU ======

 Delft3D is Open Source Software and facilitates the hydrodynamic (Delft3D-FLOW module), morphodynamic (Delft3D-MOR module), waves (Delft3D-WAVE module), water quality (Delft3D-WAQ module including the DELWAQ kernel) and particle (Delft3D-PART module) modelling. The source code can be downloaded here: [[https://oss.deltares.nl/web/delft3d]].

======Install Delft3D======

With all the necessary dependencies installed, we can now download, compile and install Delft3D. Note that you must have a Deltares SVN server account to download the source code. If you need to register, see the "Steps needed to use the Delft3D source code" section of the Delft3D compilation guide. In the compilation instructions below, replace <username> and <password> with the SVN login details that Deltares sent you. The commands below will install tag 68819, the recommended tag for Delft3D-FM. This time the binaries are placed /home/apps/chpc/earth/Delft3D/bin directory.

<code>
svn checkout --username <username> --password <password> https://svn.oss.deltares.nl/repos/delft3d/tags/delft3dfm/68819/ delft3dfm-68819
cp delft3dfm-68819/src/third_party_open/swan/src/*.[fF]* delft3dfm-68819/src/third_party_open/swan/swan_mpi
cp delft3dfm-68819/src/third_party_open/swan/src/*.[fF]* delft3dfm-68819/src/third_party_open/swan/swan_omp
cd delft3dfm-68819/src
./autogen.sh --verbose 
./configure --prefix=/home/apps/chpc/earth/Delft3d/delft3d
# make ds-install 
# make ds-install -C engines_gpl/dflowfm 
# cd ..
</code>

======Test Delft3D======

To test a structured mesh example, edit the run.sh file appropriately and issue the following commands: 
<code>
pushd examples/01_standard
./run.sh
popd
</code>



To test a flexible mesh example, issue the following:
<code>
pushd examples/12_dflowfm/test_data/e02_f14_c040_westerscheldt
./run.sh
popd
</code>
