Dear FOAMERs,

I plan a local (automatic) adaptive mesh refinement procedure by a scalar field as shown in the picture:



Is it possible to do local adaptive mesh refinement (AMR) with hybrid meshes in OpenFOAM, e.g. if there are hexaeder and tetraeder? Has anyone done similar things before?

Thanks for any input
Holger

Hi,

We also want to do AMR as indicated in the above post. Is there any guides on how to do this?

Regards
Bjorn

Hi Holger and Bjorn,

I'm also searching for a way to add adaptive mesh refinement to my OpenFoam solver. Did any of you have success with that topic so far?

Cheers,
Wolfgang

deepsterblue will become famous soon enough
I'm currently involved with AMR on tetrahedral meshes. It's pretty much mature, and I'm hoping to submit it to the OF-dev branch sometime (If Hrv is okay with the idea, that is...)

Sandeep,

I would be very interested to try out your AMR development for tet-meshes. Any idea when it could be submitted to the dev version?

Regards,
Rickard

This is now in OpenFOAM-1.6-ext. The contribution derives from the dynamicFvMesh class, called dynamicTopoFvMesh.

The class applies to simplical 2D and 3D meshes (i.e., triangle prisms in 2D and tetrahedra in 3D).

Take a look at the circCylinder3D tutorial in $FOAM_TUTORIALS/mesh/moveDynamicMesh/ for usage.

The class is not parallelized yet, but that is in the works.
