I noticed that the displacementLaplacian solver is absent in the windows version of both V2212 and V2306.

I first thought this was an issue with only V2212 but after installing V2306 it is just the same.

This means that the tutorial of snappyHexMesh with the iglooWithFridgesDirectionalRefinement does not work.

In the Ubuntu binaries it is there ofcourse, but not in the windows version.

How is this possible and how can I fix it?

Thanks in advance and best,
Duncan

Hi Duncan,

I see that v2212 has a solidDisplacementFoam at https://develop.openfoam.com/Develop...lacementFoam.C (emphasis on "solid"). Do you mean something else?

I do not see the relation between the igloo tutorial and the solidDisplacementFoam solver. Do I loose you here in translation?

Good to hear from you! Domenico.

Hello Domenico, I hope you are doing well!

No it is this tutorial:

OpenFOAMv2212\tutorials\mesh\snappyHexMesh\iglooWi thFridgesDirectionalRefinement

The displacementLaplacian solver is used in the 'addLayers' part of the grid generation of this tutorial.


//- Use displacementMotionSolver to shrink mesh
meshShrinker displacementMotionSolver;

//- Use laplacian for shrinking
solver displacementLaplacian;

displacementLaplacianCoeffs
{
diffusivity quadratic inverseDistance ("two.*" igloo);
}


Best,
Duncan

I found out the V2006 windows version DOES have the solver and there the tutorial works fine.

Good. Happy that it is solved.

If it's not working, raise an issue on https://develop.openfoam.com/Develop...nfoam/-/issues - the windows linkage is sometimes a bit "fragile" (ie, ugly) so it is quite possible that things are compiled and linked, but that the library is not properly loaded or loadable at runtime. Quite unlikely to get fixed for the 2312 release, but certainly good to flag it for someone to perhaps look at.

For future reference:

• https://develop.openfoam.com/Develop.../-/issues/3058
• Workaround "snappyHexMesh -lib fvMotionSolvers"
• Fixed in OpenFOAM-v2312

Note that the workaround of using the "-lib" option to add additional libraries can be really useful in other situations as well. It works much the same as adding them into your system/controlDict, but can be limited to a single application.
