ill defined diffusivity coefficient error

hossein.mashhadi · April 19, 2011, 10:43

Hi to all

can anybody help me and translate these lines for me:

void Foam:

rimitiveEntry::readEntry(const dictionary& dict, Istream& is)
{
label keywordLineNumber = is.lineNumber();
tokenIndex() = 0;

if (read(dict, is))
{
setSize(tokenIndex());
tokenIndex() = 0;
}
else
{
FatalIOErrorIn
(
"primitiveEntry::readEntry(const dictionary&, Istream&)",
is
) << "ill defined primitiveEntry starting at keyword '"
<< keyword() << '\''
<< " on line " << keywordLineNumber
<< " and ending at line " << is.lineNumber()
<< exit(FatalIOError);
}
}

i have compiled a new solver but when i try it i get the message:

ill defined primitiveEntry starting at keyword DT at line... .

does anybody know the reason?

Hello hossein.mashhadi

I would say the solver can't read the transport properties dictionary. This can have many reasons. Maybe you lack the property DT totally or there is a mistake in the writing of the numbers e.g. comma instead of point as decimal separator. It can although be the unit. Check the dictionary once again. Hope this will bring the solution.

Regards

Fabian

Dear Fabian

i taught the reason may be same as these, i have checked all these but none of them was wrong.

thanks for your reply.
