transitioning from cyclicAMI to cyclicGgi [v2312 ESI -> Extend 5.0]
 

Hello,
I had a functional case in OF ESIv2312 and I want to run it in the Extend version. The case uses non-conformal cyclic BC to create a periodic geometry (tube) between the inlet and the outlet.

• I am using non-conformal cyclic BC so the case could be applied to other meshes but my current mesh is conformal (between the inlet and outlet as it is a structured mesh).
• the creation of the cyclicAMI in ESI was taking less than a minute to run while the creation of the cyclicGgi it has been running since more than 2 days, so I assume that there is something wrong with my setup
• the log of the createPatch stayed at Initializing the GGI interpolator between master/shadow patches: inletAMI/outletAMI since 2 days
• here is an image of the inlet and outlet patches (in the simulation they have a bigger offset in Z, I moved them to show them easily (a simple translation in paraview):

• the complete geometry looks like a tube of 1 m of length in the Z axis
• here is an small snap of how I was doing it (in ESI) and I am doing it now (Extend) for creating the patches, for example for the inlet:
  ESIv2312:
  
  Code:

  ---

      {
        name            inletAMI;
        patchInfo
        {
            type            cyclicAMI;
            matchTolerance  0.0001;
            neighbourPatch  outletAMI;
            transform      translational;
            separationVector (0 0 $sep);
        }
        constructFrom patches;
        patches (inlet);
    }

  ---

  Extend5.0:
  
  Code:

  ---

      {
        name            inletAMI;
        dictionary
        {
            type            cyclicGgi;
            zone                cyclicPatchesZoneInlet;
            shadowPatch  outletAMI;
            bridgeOverlap  true;
            rotationAngle 0.0;
            rotationAxis (0 0 1);
            rotationCentre (0 0 0);
            separationOffset (0 0 1);
        }
        constructFrom patches;
        patches (inlet);
    }

  ---

• In the case of the Extended version before running the createPatch command, I have runned:
  
  Code:

  ---

  setSet -batch setBatchGgi
setsToZones -noFlipMap

  ---

  with the setBatchGgi file which looks like this:
  
  Code:

  ---

  faceSet cyclicPatchesZoneInlet new patchToFace inlet
faceSet cyclicPatchesZoneOutlet new patchToFace outlet
quit

  ---

• As my case is a simple periodic tube which the patches are translated I added the rotation sections of the cyclicGgi with a 0 angle as mentionned here: https://sourceforge.net/p/foam-extend/tickets/49/

any inputs to this issue would be appreciated...
