1 Description

Quoting from here:

This toolkit supersedes the icoFsiElasticNonLinULSolidFoam FSI solver within the solidMechanics toolbox.
This framework was presented at the OpenFOAM Workshop 2014 in Zagreb: abstract and slides.
The major improvement with regard to FSI coupling is the implementation of the IQN-ILS algorithm.
Also, the plugin approach used for the solid and fluid solvers should allow easier extension to other fluid/solid models e.g. multi-phase, compressible, plasticity, etc.

2 Installation

Valid versions:

The original source code is available here on the wiki: Fsi_31.tar.gz

Git repository based on this source code and further updated for foam-extend 3.1 and 3.2 is available here: https://github.com/wyldckat/FluidStructureInteraction

The instructions are a bit different, depending on the version of foam-extend:

Install on foam-extend 3.0
Install on foam-extend 3.1
Install on foam-extend 3.2

2.1 Install on foam-extend 3.0

To download and install, run the following commands:

mkdir -p $WM_PROJECT_USER_DIR
cd $WM_PROJECT_USER_DIR
wget http://openfoamwiki.net/images/5/52/Fsi_31.tar.gz
tar -xzf Fsi_31.tar.gz
cd FluidStructureInteraction/src/
./Allwmake

2.2 Install on foam-extend 3.1

First we have to download and unpack the source code:

mkdir -p $WM_PROJECT_USER_DIR
cd $WM_PROJECT_USER_DIR
wget http://openfoamwiki.net/images/5/52/Fsi_31.tar.gz
tar -xzf Fsi_31.tar.gz

Now we need to do some repairs in the source code:

cd FluidStructureInteraction/src/fluidStructureInteraction/stressModels/constitutiveModel
 
wget https://raw.githubusercontent.com/wyldckat/FluidStructureInteraction/fe31/src/fluidStructureInteraction/stressModels/constitutiveModel/constitutiveModel.C -O constitutiveModel.C
wget https://raw.githubusercontent.com/wyldckat/FluidStructureInteraction/fe31/src/fluidStructureInteraction/stressModels/constitutiveModel/constitutiveModel.H -O constitutiveModel.H
 
cd ../../..

Finally, we can build the toolkit:

./Allwmake

2.3 Install on foam-extend 3.2

The changes needed for foam-extend 3.2 are too many in order to reuse the file provided for foam-extend 3.0, therefore here are the instructions for getting from wyldckat's repository at Github:

Go into the assigned user folder:

mkdir -p $WM_PROJECT_USER_DIR
cd $WM_PROJECT_USER_DIR

Now, depending on whether you're able to use git or not:

For cloning from the git repository:

git clone https://github.com/wyldckat/FluidStructureInteraction.git

Then checkout the right branch:

cd FluidStructureInteraction
git checkout fe32

For downloading the ZIP package:

wget -O FluidStructureInteraction.fe32.zip https://github.com/wyldckat/FluidStructureInteraction/archive/fe32.zip

Then unpack, rename the unpacked folder and go into the folder:

unzip FluidStructureInteraction.fe32.zip
mv FluidStructureInteraction-fe32 FluidStructureInteraction
cd FluidStructureInteraction

Now build:
```
cd src
./Allwmake
```

3 Tutorials

The toolkit provides in the folder run the following examples:

fsiFoam
- 3dTube
- beamInCrossFlow
- HronTurekFsi3
stressFoam
- plateHole
thermalStressFoam
- flange

3.1 fsiFoam tutorial cases

Each tutorial case available in the fsiFoam folder is executed by running the following commands:

sed -i s/tcsh/sh/g *Links
./removeSerialLinks fluid solid
./makeSerialLinks fluid solid
cd fluid
./Allclean
./Allrun

3.2 stressFoam tutorial case

The tutorial case plateHole is executed by going into the case folder:

cd stressFoam/plateHole/plateHole/

And running:

./Allrun

3.3 thermalStressFoam tutorial case

The tutorial case flange is executed by going into the case folder:

cd thermalStressFoam/flange/
