boundary conditions for contact regions

attanikal · May 22, 2018, 07:19

Hi all

I imported a 3D geometry of a reactor with impellers from fluent into OpenFOAM and wanted to use k-epsilon model. I found patches named contact_region-src and contact_region-trg on the constant/polymesh/boundary directory.

What boundary conditions shall i give for these contact_region-src & trg for k and epsilon.

it's called AMI in openFoam. search the forums for createPatch.

Hi,

You shall use createPatch to connect the surfaces to each others. There you can define AMI-type boundary condition.
