Particle Tracking across GGI Interface

strakakl · July 2, 2012, 05:27

Hi foamers,

i try to track particles across a GGI interface but it seems that the particles escape at the GGI patch. Does anybody know if tracking across a GGI interface works "out of the box" in OpenFOAM 1.6-ext and how to set it up?
Or do i have to modify the code to get this running.

Best regards,
Klaus

Hi strakakl

I don't think the particles will be tracked over the GGI interface at the moment. However, I got a question. When you do your particle tracking, are you using the icoLagrangianFoam to track the particles or you have to modify to reading the dynamic mesh while it is tracking?

Thanks

sorry for the late reply, i was on vacation

. I use a modified version of the transientSimpleDyMFoam solver.
Tracking across the ggi interface is not possible, i think the reason is that there is no explicit handling of ggi patches in the tracking algorithm. I try to find out how to handle the ggi patches but the code is a little bit tricky.

best,

Klaus
