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 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

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

Finally, we can build the toolkit:

./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/

And running:

./Allrun

4 Reports where this toolkit has been used

The following entries are in the page for the 2014 MSc/PhD course in CFD with OpenSource software at Chalmers University of Technology, which use this toolkit:
