conductivity in chtMultiRegion
 
hi,

i try to use chtMultiRegion for a multi region with thin elements.
the thin elements isnt a region (NO MESH! for this region).
But the target is to simulate this too.
normaly i use a diffrent k (therm.conductivity) an the patches.
but in the chtmultiregionsimplefoam I cant set a boundary with a
other value as the region himself. I try, of course, to set the patch
with fixedValue or other, not work! as second step i use funkysetfields
for a complete cell definition of K in a specially area, but its also not work.

can everyone give me a clue for this problem?

thanks
sven

Hello,

If you think to shell conduction (thin sheets, no mesh inside), i'm afraid that Openfoam doesn't have this capabilities (yet ?).
So you should mesh the wall, and use chtmultiregion ..
