hello,I started to leran openfoam.i have proplem when i work with chtregion simplefoam and i cant solve this error.
this error is:
Create time



--> FOAM FATAL IO ERROR:
keyword regions is undefined in dictionary "/home/sahar/Desktop/fasle4/constant/regionProperties"

file: /home/sahar/Desktop/fasle4/constant/regionProperties from line 18 to line 20.

From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 402.

FOAM exiting

Dear,
error is written there , you should look for the keyword region at file regionProperties at the given address.

Thanks,but now i found other problems,can you help me?i cant understand these error.
my errors are:

it seem it relates your choice of thermoPhysicalProperties

Foam::heRhoThermo<Foam::rhoThermo, Foam:ureMixture<Foam::constTransport<Foam::speci es::thermo<Foam::hConstThermo<Foam:erfectGas<Foa m::specie> >, Foam::sensibleEnthalpy> > > >::calculate() in "/opt/openfoam220/platforms/linux64GccDPOpt/lib/libfluidThermophysicalModels.so"

1- whats your choice?
2- does your test case run at all?

Hi,thanks.i try to solve your books example in chapter 4(conjugate heat transfer).i check my thermophysicalproperties with your books but i cant find problem.no my test dosent run.

Try the tutorial put in dvd, with the same openfoam version ;-)
