Hello,

while i compile my case, the compiler display the error

Time = 5

--> FOAM FATAL ERROR :
gradientInternalCoeffs cannot be called for a defaultFvPatchField (actual type AdjVelocityBoundary)
on patch inlet of field V in file "/users/studi8/OpenFOAM/studi8-1.4.1/tutorials/ObjectAdjFuncFoam/testcase/5/V"
You are probably trying to solve for a field with a default boundary condition.

From function defaultFvPatchField<type>::gradientInternalCoeffs( ) const
in file fields/fvPatchFields/basic/default/defaultFvPatchField.C at line 694.

FOAM exiting

I dont know how to solve these problem, the compiler displays, or how i solve for a field with not-default boundary condition.

Thanks!

Regards,
Khaled

Hi,

I am not so sure about it but have a look in the boundary file. Maybe your patch defination is wrong. Should be a "wall" patch or only "patch"...

Khaled,

As the message says, "You are probably trying to solve for a field with a default boundary condition."
This likely means that your boundary condition hasn't been linked in at all.

To trap this case, you can set
> disallowGenericFvPatchField 1;
in the etc/controlDict. After you've found the problem, it is best to switch this back to zero - otherwise the paraview reader module will complain about lots of unknown boundary conditions.

Hello Mark,

you mean i have to trap
> disallowGenericFvPatchField 1
in my dictionary /controlDict ?

Is there any other possibilities?

Thanks Mark!

Regards,
Khaled

Hi,

i have found the problem. I have forgotten to set

makePatchTypeField(fvPatchVectorField,...);

so that my boundary condition has now be linked!

hi，
i have the same problem,but i have no idea what i can do even i saw the messages,would you tell me how to do in detail?

HELLO
I AM CREATING COMBUSTOR MODEL, I ENTERED VERTICIES AND I CREATED PATCHES AS INLET, OUTLET, TOP WALL, BOTTOM WALL, AND EMPTY FRONTANDBACK, WHILE EXECUTING FOAM IS SHOWING FATAL ERROR, FOAM EXISTING.. PLEASE GIVE ME THE GUIDELINES

[vijayakumar]

i am new user, i dont know sir, u people has to guide me in the right path, read your sentences once, is that right way of guiding, i am sorry for my mistake , i need to run a combustion problem.... i used XI-foam as solver of openfoam1.4 version, i created verticies, block mesh is executed, while running some errors are showing, i want to know is that a correct solver or not, and brief description to give initial boundary conditions, and how to define field values.
below i sown my blockmesh dict

Hi Khaled,

I have the same problem. Could you please let us know more details about how you linked your boundary condition. for example where did you set makePatchTypeField(fvPatchVectorField,...);

Thanks,
Ali
