Hi,

I am trying to use the packed function object flowRate with chtMultiRegionSimpleFoam and it fails with

--> FOAM FATAL ERROR: 

    request for objectRegistry region0 from objectRegistry heatExchanger failed
    available objects of type objectRegistry are

2
(
air
porous
)


    From function objectRegistry::lookupObject<Type>(const word&) const
    in file /home/openfoam/OpenFOAM/OpenFOAM-2.4.0/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 198.

FOAM aborting

#10  ? at ??:?

I followed the guidlines given in
http://cfd.direct/openfoam/user-guide/function-objects/
under 6.2.2
using heatExchanger tutorial-file
It seems that there are problems because of the multi-domain characteristics of this case.
Does anybody know a solution for this?

Quick answer:

1. Edit your local copy of the file "flowRatePatch".
2. Change this:
   

   flowRatePatch
   {
       patch <patchName>;
   
       #includeEtc "caseDicts/postProcessing/flowRate/flowRatePatch.cfg"
   }

   To this:
   

   flowRatePatch
   {
       patch <patchName>;
   
       #includeEtc "caseDicts/postProcessing/flowRate/flowRatePatch.cfg"
   
       region <regionName>;
   }

3. Replace "<regionName>" with the region name you want.
