Dear Foamers,

I am trying to simulate flow across a channel, which has an absorber plate in it (rough schematic attached). I have also atttached the case. Currently, I getting this error.

Code:
#0  Foam::error::printStack(Foam::Ostream&) at ??:?
#1  Foam::sigFpe::sigHandler(int) at ??:?
#2  ? in "/lib/x86_64-linux-gnu/libc.so.6"
#3  Foam::heRhoThermo<Foam::rhoThermo, Foam::pureMixture<Foam::constTransport<Foam::species::thermo<Foam::hConstThermo<Foam::perfectGas<Foam::specie> >, Foam::sensibleEnthalpy> > > >::calculate() at ??:?
#4  Foam::rhoThermo::addfvMeshConstructorToTable<Foam::heRhoThermo<Foam::rhoThermo, Foam::pureMixture<Foam::constTransport<Foam::species::thermo<Foam::hConstThermo<Foam::perfectGas<Foam::specie> >, Foam::sensibleEnthalpy> > > > >::New(Foam::fvMesh const&, Foam::word const&) at ??:?
#5  Foam::autoPtr<Foam::rhoThermo> Foam::basicThermo::New<Foam::rhoThermo>(Foam::fvMesh const&, Foam::word const&) at ??:?
#6  Foam::rhoThermo::New(Foam::fvMesh const&, Foam::word const&) at ??:?
#7  ? at ??:?
#8  __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6"
#9  ? at ??:?
Floating point exception (core dumped)
Please help me out with this issue.

Thanks.

Bloerb will become famous soon enough
Most of your boundary condtions are set up wrong. Your Allrun script does not call changeDictionary for one region, you have no fvSolution and fvSchemes in your region folders etc....

Attached is a cleaned up version. Might not work with your 2.1.x release. I recommend upgrading. Otherwise you should be able to tell which changes have been made.

Thank you so much Bloerb. I apologise I had attached an older version of case file. I tried to run the case you attached. It is not running. Can you tell me what's missing. Again, thank you for replying.

It is giving error


--> FOAM FATAL ERROR:
cannot find file "/home/rudh/Desktop/SAH2/0/wall/p"

From function virtual Foam::autoPtr<Foam::ISstream> Foam::fileOperations::uncollatedFileOperation::rea dStream(Foam::regIOobject&, const Foam::fileName&, const Foam::word&, bool) const

FOAM exiting

I have figured it out. Thankyou again Bleorb. In the new case that you have sent and my case the only difference was that I was not including the script to call changeDictionary. This issue I have resolved now. Thank you very much.
