Hey Takuy,
that is indeed pretty worrying. I will test it with my icoFsiFoamsolver and report, if I find the same problem. I actually built it from scratch, referring to Karl Jacob Maus manual. I guess it yet is exactly the same as jasaks solver. @matteo, I am trying very hard to run icoFsiFoam parallel. However, I am very new to all the parallelization stuff in openFoam and hence find it hard to start. If I decompose both the fluid and the structure to the same numbers of processors from the .fluidfolder, the solver starts, but stops immediately before having finished the first time step. Code:

Hi Thriceguy,
In fact we're finding the problem is not so simple and straightforward as I've reported (fixing the surfacetosurface interpolation caused another problem). In any case 1.6ext has just been released; let's see how the "Updated fluidstructure interaction solver with parallelisation support" works Takuya

Hey Takuya,
that's good news. I will run some simulations with it, too. We'll see and hope the best ;)! David

Hi,
are there any updates with the parallelization of the icoFsiFoam solver? I tried the last version from the 1.6ext git and the flappingConsole still does not run in parallel. I tested where the error occured and think this is already in the volPointInterpolation (cpi) of the setMotion.H. The patchToPatch interpolation also does not work in parallel, but we could switch over to a directMappedBased boundary condition (like the turbulentTemperatureCoupledBaffleMixed which is used in CHTMultiRegionFoam  this one works also in parallel) in order to couple fluid and solid patches. Any idea how to get this solver working in parallel?

looks like blockMesh came up with the error in the first place.

@ PeterII
You need to take the latest RunFunctions from http://openfoamextend.svn.sourcefor...ext/bin/tools/ and replace it with your RunFunctions in bin/tools/ Moreover comment out these lines in Allrun Code:
#cd constant #ln s ../../solid/constant solid #cd .. #cd 0 #ln s ../../solid/0 solid #cd ..

Thank you (ZKM) so much for this help. However the blockMesh log file show the this error:

icoFsiFoam problem with decomposed patches

Hi everybody,
I'm new to this Forum, but have some experience with OpenFOAM. I'm interested in Fluid Structure Interaction and am currently testing the icoFsiFoamSolver from the OF1.6ext version. In serial mode the tutorial and several other cases are working fine, but if it goes to parallel the results do not match the serial ones. The deformation of the solid in parallel (in some cases) is far less than expected. The problem occurs when the fluid/solid patch is on 2 or more processors. If the fluid/solid patch is only on one processor the parallel and serial cases match perfectly. My questions are, if somebody else has the same problem and if there is any solution? Thanks in advance! Best regards, Daniel PS: The Problem can easily be reproduced with the standard tutorial for icoFsiFoam (flappingConsoleSmall). For the decomposeParDict the following can be used (it is only important that the fluid/solid patch is split!): numberOfSubdomains 4; method simple; simpleCoeffs { n (1 4 1 ); delta 0.001; }

Hi everyone,
You can find here a new solver that I am trying to make for fluidstructure interaction. I am working on version 1.6ext. This solver included: 1/ pimpleDyMFoam in which we have ALE and turbulence models can be used 2/ outer fixed point adaptive relaxation by using Aitken's method for strong coupling 3/ solve transport equations for heat and mass transfer 4/ solid solver for large deformattion (2nd PiolaKrichhoff stress tensor...) 5/ computing traction in setPressure.H but it is not taken into account in tractionDisplacementFvPatchVectorField.C can you give some hint please Can you try this solver on the attached testCase and give me remarks because I am sure there will be some mistakes especially for: 1/ Aitken's method 2/ solid solver and its part in tractionDisplacementFvPatchVectorField.C 3/ setting traction in tractionDisplacementFvPatchVectorField.C Thank you in advance. Charbel.

Dear All,
could you help me please where can I find icoFsiFoam solver in OpenFOAM 2.2.1. I searched many times but unfortunately I didn't get any result. Also, I tried to make my FSI directory but the same it is not working. Help me please to find the answer. Regards

Many thanks for your reply. I have some questions regarding your answer
1. Have I install OpenFOAM 1.6ext inside OpenFOAM 2.2.1 that I had installed before or install it separately? 2. During installation I got some error, how can I reinstall it again? 3. I got locked folders, OpenFOAM 1.6ext locked, why? 4. How to work with fluid and solid in parallel in cases such that flappingConsoleSmall? Many thanks for your helping.

FVM and FEM FSIOF1.6ext

Hi
Iam using pimpleFsiFoam solver for pitching motion of naca0012 airfoil in incompressible and turbulence flow.My problem is weak coupling. PimpleFsiFoam is a solver based on FEM. So for moving the airfoil by pointDisplacement, I converted it to FVM. I create 2 meshes in gambit, one for the fluid and another one with the airfoil only as my solidMesh. Then convert them using fluentmeshToFoam. Various mesh for y + <1 is tried and boundary conditions for U and P are: U: Code:
dimensions [0 1 1 0 0 0 0]; internalField uniform (13.7873 2.431 0); boundaryField { outlet { type zeroGradient; } inlet { type fixedValue; value $internalField; } airfoil { type movingWallVelocity; value uniform (0 0 0); } Code:
dimensions [0 2 2 0 0 0 0]; internalField uniform 0; boundaryField { outlet { type fixedValue; value uniform 0; } inlet { type zeroGradient; } airfoil { type zeroGradient; } Do Solver wrong acts or the case is problem? Geometry with coarse mesh and without motion and laminar flow was ran only by icoFsiFoam openfoam tutorial solver. For turbulent flow,I convert icoFsiFoam to pisoFsiFoam. But again, I fail. How do I apply this motion in the FEM solver? Last edited by wyldckat; December 1, 2013 at 09:36. Reason: Added [CODE][/CODE]

Seeing a similar error PeterII experienced, and ZKM suggested a solution for.
Different situation  in that I'm adapting the icoFsiFoam solver to use a different solid domain solver. The error I see is: Code:
> FOAM FATAL IO ERROR: keyword grad(U) is undefined in dictionary "/home/eric/foam/eric3.0/run/ applications/solvers/icoFsiElasticAcpSolidFoam/tutorial/fluid/system/fvSchemes::gradSchemes" So could anyone shed some light on the underlying reason for ZKM's proposed solution: Quote:

I solved HronTurekFsi case in OF Extend 3.1
for many time steps but i stoped the solver to show it in paraFoam. It appears fluid domain only without solid

Hi friends,
I could impose motion on solid patch by applying oscillatingFixedValue BC in motionU file and solid moves properly.But unlike the solid, fluid patch moves in the opposite direction of solid patch. Solver is icoFsiElasticNonLin... in foamextend3.1. My test case is uploaded on: http://www.uploadbaz.com/f4xg5rf6b2rv Where is the problem? Can someone help me? Christoph, I have a specific question from you. I want to impose a forced oscillatory motion on solid,According to your thread in post #10. Can you tell me how did you apply that motion?
