Moving mesh

flowris · June 21, 2011, 11:50

Hello,

I am trying to move a mesh using GGI, and a homemade dynamicFvMesh class. A foil is inside a circular mesh, which rotates inside a static square mesh. On the circular interface the ggi is done.

Two zones (insideZone and outsideZone) are present, like the mixer case. The problem is now that only a part of the nodes of the insideZone move, the rest stays, see pictures.

Can anybody tell me what happens, or give more general explanations?

Hi flowris,
my guess: your insideZone/outsideZone files are not in sync with your mesh.
Did you refine your mesh recently ?

Thank you. That was my guess too, but everytime I run the case I start with
setSets -batch setBatch
setsToZones -noFlipMap

just as it is done in the mixerGgi tutorial. I get correct constant/polyMesh/setsinsideZone and outsideZone files.

Anyway, I did the procedure again and now it seems to work. I don't know what the difference is. Maybe my head is just clearer this morning
