chtmultiregion startFace

yossi · March 18, 2011, 12:49

hello,

running chtMultiRegionFoam I get the following output:

"
Create time

Create fluid mesh for region topAir for time = 0

Create solid mesh for region heater for time = 0

--> FOAM FATAL IO ERROR:
keyword startFace is undefined in dictionary "::zones"

file: ::zones from line 55 to line 55.

From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 395.

FOAM exiting
"

but I don't know which file or dict to look for 'startFace'

Does anyone know if this is BC problem or what cause this error?

thanks,

Hi Yossi,

I don't know if it helps, but I had a similar problem - though it was not in zones but in minX. I simply had tried to implement another geometry and had taken over all of the names, patches, etc...

The entry "startFace" in my case was missing within bottomAir/polyMesh/boundary .
Entering the entries for nFaces and startFace (and doing similar in a few initial solutions within the 0-folder) did make the simulation cross that point at least.
Perhaps that already works for you?

In my case though the simulation failed afterwards with a segfault, because I was doing weird things with the geometry. ;-)

Hi Bernard,
thank you for your replay.
it exactly as you described, and I've solved it.

thank you!
