Hi dear Foamers
I wanna use timevarying BC in OF 2.1.1
My solver is icoFoam and I use ubuntu 12.04
0\U file is:

   inlet   
    {
       type          uniformFixedValue
     uniformValue     table
(
    (  0   0.0)
    (100  10.0)
); 

    }

and the error is :

Reading field U

--> FOAM FATAL IO ERROR: 
keyword uniformValue is undefined in dictionary "/home/amin/OpenFOAM/amin-2.1.1/run/arterioleNewtonian/0/U::boundaryField::inlet"

file: /home/amin/OpenFOAM/amin-2.1.1/run/arterioleNewtonian/0/U::boundaryField::inlet from line 25 to line 26.

    From function dictionary::lookupEntry(const word&, bool, bool) const
    in file db/dictionary/dictionary.C at line 400.

FOAM exiting

I'm so confused. what should I do?

I found my answer here:

I founded my fault . I should change to this for velocity:

inlet
{
type uniformFixedValue
uniformValue table
(
( 0 (0 0 0.0))
(100 (0 0 10.0))
);
}

hi amin,
I think you should have to change your uniformFixedValue to timeVaryingUniformFixedValue. Then it will work.

Thanks

Mallikarjuna,

TimeVaryingUniformFixedValue is an old BC that does not work in new versions of OpenFoam.
