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
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:
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
