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

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

[lr103476]

I mean (the forum software is also playing games with me):

Info <<this->currentScale() << endl;

Is there a way to call this currentscale value from my own user solver. I dont like to recompile the complete finiteVolume.so again and again....

Regards, Frank

[lr103476]

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

[lr103476]

I just discoverd that there is no source for:

src/tetDecompositionFiniteElement/tetPolyPatchFields/derivedTetPolyPatchFields/o scillatingFixedValue

in the standard OpenFOAM 1.3 distribution, but it is in your development code. 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

[lr103476]

Has someone else got this oscillatingFixedValue boundary condition working using icoDyMFoam??

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 'out-of-the-box' OpenFOAM 1.3?

Regards, Frank

[soup]

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

[lr103476]

Hi Bryan,

I justed returned from holiday. Before that, I did not succeed in recompilating of prof. Jasak's development sources. This month I try again. Then I hope that the icoDyMFoam will work in combination with the oscillatingFixedValue boundary conditions.

Frank

[irc]

Frank - perservere with the compilation. It's worth it - I have a simple oscillating cylinder test case that works beautifully with Hrv's latest version of the code. I too had some difficulty with the compilation (on RHEL AMD64) - I can maybe help out if you get stuck.

[lr103476]

Ok, I succeeded in recompiling OpenFOAM-1.3 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 OpenFOAM-1.3 sources, the oscillatingFixedValue boundary condition does not work.

I'll keep you posted.

Regards, Frank

[irc]

I think there's a more fundamental fault with the dynamic mesh solver in the standard OpenFOAM-1.3 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.

[hjasak]

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.

Sorry :-(

Hrv

[lr103476]

But, you do include your correct sources in the next version 1.4, right?

Regards, Frank

[lr103476]

Hi Ian Cowan,

Could you possibly share some of your settings concerning your oscillating cylinder test case.

For example, what kind of mesh do you use, how is it moved, which mesh diffusion solver did you use and what are the timesteps?

Thanks and regards, Frank

[irc]

Frank

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!

Ian

[lr103476]

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 Crank-Nicholson, what CN coefficient did you use, 0.5, 1.0 or something in between?

Regards, Frank

[hjasak]

Well, I recently did some fluid-structure 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 21-23/Sep/2006. There is also a paper, but without too much detail (it's more general OpenFOAM and FSI stuff).

Hrv

[lr103476]

Dear prof. Jasak,

I succesfully compiled your latest sources: OpenFOAM-1.3_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.

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?

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 trace-back, using dgb
- if you ask me nicely, you can pass over your case and I will find out what is going wrong.
