WHen I again use your example of oscillatingCavityMesh from 3 post above, still no motion is solved.
=============================================== The output is for every timestep something like: Nprocs : 1 Create time Create mesh for time = 0 Selecting motion solver: laplaceTetDecomposition Selecting motion diffusion: constant Value of constant motion diffusion: 1 Time = 0.005 ICCG: Solving for motionUx, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUy, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUz, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUx, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUy, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUz, Initial residual = 0, Final residual = 0, No Iterations 0 ExecutionTime = 0.06 s ClockTime = 0 s Time = 0.01 Correct mesh motion diffusion field. ICCG: Solving for motionUx, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUy, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUz, Initial residual = 0, Final residual = 0, No Iterations 0 ExecutionTime = 0.08 s ClockTime = 0 s =============================================== Any ideas?

So to output the frequency, amplitude or the currentScale values, I have to put a statement like:
Info <<>currentScale() << endl; in the oscillatingFixedValue.C. This means that I have to recompile finiteVolume.so. Is this the only way, I like to leave the original source code untouched. Isn't it possible to call the variables from oscillatingFixedValue from my own user solver. Frank

Dear prof. Jasak,
Still no motion occurs using your example. I tried different boundary condition combination, no success. I notices that you use in your example: solverLib "libtetDecompositionMotionSolver.so", but I've only got: solverLib "libtetDecompositionMotionSolvers.so", (not the extra "s"). So, besides the name did you also changed the contents of this motion library, which could possibly cause my problems? Btw, I assume that solverLib is used by moveMesh, but that dynamicFvMeshLib is used to really solve the flow with icoDyMFoam. Is this true? Further, I really want to solve this problem soon, since apparently no user of the standard OpenFOAM 1.3 is able to solve flows with oscillatingFixedValue boundary conditions, which can be applied to a lot of fun applications.... Regards, Frank

Therefore I'll try to include your piece into OpenFoam 1.3 in order to see what happens. You also appended the tetDecompositionMotionSolver with some tetPolyMeshMapper stuff. What is the purpose of that stuff? Regards, Frank

At this time I am recompiling openFoam with prof. Jasak's development sources, but recompiling is not as easy as it seems. Maybe there is some other workaround for my problem using the standard 'outofthebox' OpenFOAM 1.3? Regards, Frank

Hi Frank Bos,
Were you successful in getting the example working? I have tried but get an error related to that library also: > FOAM FATAL ERROR : could not load libtetDecompositionMotionSolver.so: cannot open shared object file: No such file or directory From function motionSolver::New(const polyMesh& mesh) in file motionSolver/motionSolver.C at line 117. I guess I just don't have the right library all together. If you were successful could you please post the steps you took? Thanks, Bryan Godbolt

Ok, I succeeded in recompiling OpenFOAM1.3 with the prof. Jasak's sources (from a month ago, I cannot reach his release site for the latest sources??).
The oscillatingFixedValue boundary condition seems to work in combination with icoDyMFoam, but I have to test it further using proper cases. But it remains strange that using the standard OpenFOAM1.3 sources, the oscillatingFixedValue boundary condition does not work. I'll keep you posted. Regards, Frank

I think there's a more fundamental fault with the dynamic mesh solver in the standard OpenFOAM1.3 distribution. For example, I found that using icoDymFoam to model the flow around a stationary cylinder, with a stationary mesh and a simple fixed wall BC, gave me junk  just potential flow around the object. Hrv's new version of the code fixes some fundamentals, and all is then well.

Yup, it has actually been validated on test examples for accuracy. I cannot remember the bug fix (it was nasty, that I do remember) so I'm afraid no patch this time.

My mesh is rather simple at the moment  I am running at very low Re with a coarse mesh, to prove the concept. I'll refine later on, once I've worked out how to morph just part of the mesh (that bit immediately around the cylinder), rather than the whole mesh; the mesh movement takes rather a lot of CPU otherwise, which is not great for lengthy transient calculations. For the movement, I've started off enforcing a sinusoidal motion, using motionU through some additional code that I call on each time step in icoDyMFoam. Search for motionU on the message board. It's easy to get the feedback from the flow, ie. to make it an FSI simulation, but I'm taking one step at a time. Note that the current version of OF seems to have a problem with wall BCs  again check the messages. You'll need Hrv's development version for it to work correctly. As for dynamicMeshDict settings, I've used the following to date: dynamicFvMeshLib "libtetDecompositionMotionSolvers.so"; dynamicFvMesh dynamicMotionSolverFvMesh; twoDMotion yes; solver laplaceTetDecomposition; diffusion quadratic patchEnhanced; frozenDiffusion off; As ever, dynamic mesh movement with OF is like white water rafting  strap yourself in for a bumpy ride, but it's worth it in the end!

Thanks for your reaction. I'm working on a similar problem. First I will simulate an oscillating 2d cylinder at large amplitudes (translation and rotation). I succeeded in version 1.2, but in 1.3 it is almost working.
Than I want to simulate a 2d flapping wing wich is also capable of passive deformation, so fluid structure interaction. Finally I want to extend this problem to a moving 3d wing. These problems are rather ambitious, but we'll see how far I get. What are your amplitudes, frequencies and timesteps? If you are using CrankNicholson, what CN coefficient did you use, 0.5, 1.0 or something in between? Regards, Frank

Well, I recently did some fluidstructure interaction work which seems to cover all your stuff. You can, of course, throw out the actual structures solution and just use the code to run the fluids side if you know the boundary deformation.
Some of this will be presented in my lecture at the 5th International Congress of Croatian Society of Mechanics in Trogir, Croatia 2123/Sep/2006. There is also a paper, but without too much detail (it's more general OpenFOAM and FSI stuff). Hrv

Dear prof. Jasak,
I succesfully compiled your latest sources: OpenFOAM1.3_03_09_06.tgz, but again there is a problem concerning a solver using mesh motion. When using for example icoDyMFoam on the movingCone tutorial there arises a segmentation fault. ============================================== ============================================== Selecting dynamicFvMesh dynamicMotionSolverFvMesh > FOAM Warning : From function dynamicFvMesh::New(const IOobject&) in file dynamicFvMesh/newDynamicFvMesh.C at line 90 library "libtetDecompositionMotionSolver.so" did not introduce any new solvers Selecting motion solver: laplaceTetDecomposition Selecting motion diffusion: quadratic Reading transportProperties Reading field p Reading field U Reading/calculating face flux field phi Starting time loop Courant Number mean: 0 max: 0.3 Time = 5e06 ICCG: Solving for motionUx, Initial residual = 0.303132, Final residual = 9.89834e07, No Iterations 1885 ICCG: Solving for motionUy, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUz, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUx, Initial residual = 4.54029e06, Final residual = 9.46537e07, No Iterations 185 ICCG: Solving for motionUy, Initial residual = 0, Final residual = 0, No Iterations 0 ICCG: Solving for motionUz, Initial residual = 0, Final residual = 0, No Iterations 0 Segmentation fault ============================================== ============================================== It is annoying to keep on debugging everytime a new (development) version is available. Is there a (development) version available in which the problems occuring with the standard OF version 1.3 are solved without introducing new errors? Regards, Frank

Well, this works for me, the motion solver did its job well and I cannot tell you anything further based on the data. You can do two things:
 produce a complete traceback, using dgb  if you ask me nicely, you can pass over your case and I will find out what is going wrong. Hrv
