Dear GGI experts and FOAMers,

I am trying to simply add GGI rotations and vertical translations (using movingConeTopoFvMesh), which seems very straightforward. I basically copy the mixerGGIMesh code into movingConeTopoFvMesh. But, the snapshot (attached here) shows uncovered GGI facets after a few time steps. I could not find the source of the problem as every thing seems to be simple, but I appreciate any hint from the experts. I am not even sure if this is a bug in my version of OF-dev (I am using an old version as I do not have the permission to upgrade) or that's just a stupid mistake I am making . I will gladly post every thing here if someone wants to take a look or if someone is willing to give it a try and make sure this is my mistake not some kind of bug.

Looking forward to having some kind of response

Hi Again,

I post the case and the motionLib here. Does any one know where the GGI rotation origin is defined? Unfortunately I cannot post the movie here as it's too big..
If you look at the attached lib, I have basically added the two mesh libs of GGI and movingCone. I think that I am not updating the GGI origin for rotation and that's why there are uncovered faces (please correct me if I am wrong). Has any one tried to update the GGI rotation origin when there is translatinoal motion as well. The cs().origin() in the GGI code is just (I think) used for the cell definition and for the points's markup of the insideSlider to rotate.

Hello Reza,

With thanks to the Summer School in Zagreb, I send you here a dynamicFvMesh adaptation that combines GGI with a deforming mesh: a cylinder around an object does not deform, but can translate and rotate, while the mesh around it deforms.
