Hi all,

I am modelling at free surface flow around a circular cylinder, and wanted to test if using a dynamic mesh provides better results (or the same results faster) compared to adding refinement regions.

As far as i understand, dynamicMesh is implemented in interFoam now, i.e. interDyMFoam is not neede as an application entry in controlDict..

I have inserted a dynamicMeshDict into the constant folder, however i get the following error message:

PIMPLE: iteration 1 Selected 28439 cells for refinement out of 5438309. Refined from 5438309 to 5637382 cells. Selected 0 split points out of a possible 28439.

I cant really see where the error is.

It is important to note that if i run interFoam without the dynamicMeshDict in the constant folder, the case runs normally... What am i missing? Is there an initialization i haven't done prior to using the dynamicMesh?

For reference, the dynamicMeshDict is as follows:


FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "constant";
object dynamicMeshDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dynamicFvMesh dynamicRefineFvMesh;

dynamicRefineFvMeshCoeffs
{
// How often to refine
refineInterval 1;
// Field to be refinement on
field alpha.water;
// Refine field inbetween lower..upper
lowerRefineLevel 0.1;
upperRefineLevel 0.99;
// If value < unrefineLevel unrefine
unrefineLevel 10;
// Have slower than 2:1 refinement
nBufferLayers 1;
// Refine cells only up to maxRefinement levels
maxRefinement 2;
// Stop refinement if maxCells reached
maxCells 6000000;
// Flux field and corresponding velocity field. Fluxes on changed
// faces get recalculated by interpolating the velocity. Use 'none'
// on surfaceScalarFields that do not need to be reinterpolated.
correctFluxes
(
(phi none)
(nHatf none)
(rhoPhi none)
(alphaPhi0.water none) //Inserted due to error provided by OpenFOAM
(alphaPhiUn none) //Inserted due to error provided by OpenFOAM
(ghf none)
);
// Write the refinement level as a volScalarField
dumpLevel true;
}


// ************************************************** *********************** //

I appreciate your time!

/Rasmus

%%---------------------------EDIT--------------------%%
I've included:
"cellDisplacement.*"
{
solver GAMG;
tolerance 1e-5;
relTol 0;
smoother GaussSeidel;
cacheAgglomeration true;
nCellsInCoarsestLevel 10; agglomerator faceAreaPair;
mergeLevels 1;
}

In the fvSolution, which reduced the first error I've listed to only being shown once instead of the two errors starting with *** Process received signal ***...

have you tried to run an interfoam tutorial with dynamic mesh to be sure it does not come from the installation?



I see the keyword win10 in the log. Do you use an openfoam windows10 version?

Hi, thank you for reading my (way too long) question!

?
Yeah, I've tried running dambBreakWithObstacle which seems to fine just fine.

No I am running on ubuntu, it is just installed through powershell on windows10.

Ok, your mesh is 3D? (because dynamicMesh support only 3D mesh)


Is it based on tetra or hex?

Oh, i didn't know that. But yes, the mesh is in 3D.

in fvSolution, there is the pcorr section, but your log says that everything is fine...
I have no idea.

Okay, well thank you for trying anyway! I've found a post suggesting it might be a problem with lack of memory, mpirun problems: exited on signal 11 (segmentation fault)

I am trying to run the same case on a bigger computer. If it works, i'll let you know.

Ha! I thought about the memory problem, but I can not think that it is the problem because the refinement is not huge.
You are passing from 5438309 to 5637382 cells.

Now i am dealing with a floating point exception..

FPE == division by 0... Perhaps a problem with the mesh (a cell with zero volume)? What is the output of checkmesh?

mengge is on a distinguished road
hi, i am encountering the same problem with Floating point exception, do you have any idea on how to solve that?
and it doesn't seem like something is wrong with checkmesh.

Thanks.
