Hi. Everybody.
I'm a new openFoam user. so i can not launch this case. I don't know how to fix the error. Can you help please.
This is case (case of an master thesis which downloaded from web http://www.tfd.chalmers.se/~hani/kurser/OS_CFD/)
thanks a lot!
======
This is error:
--> FOAM FATAL IO ERROR:

Cannot find 'value' entry on patch rotor_cyclic_upper of field p in file "/home/minh/Desktop/turboPassageRotating2D/0/p"
which is required to set the values of the generic patch field.
(Actual type cyclicGgi)

Please add the 'value' entry to the write function of the user-defined boundary-condition


file: /home/minh/Desktop/turboPassageRotating2D/0/p.boundaryField.rotor_cyclic_upper from line 43 to line 43.

From function genericFvPatchField<Type>::genericFvPatchField(con st fvPatch&, const Field<Type>&, const dictionary&)
in file genericFvPatchField/genericFvPatchField.C at line 71.

FOAM exiting

Please show to me, thankS!

Can you post the pressure boundary condition file of your case (since that's where the problem is occurring)?

As a side note, I think the title of your post is a bit misleading.

All the best,

A

ThankS.
This is my pressure boundary condition.

Alright, I think you're using an older version of FOAM since you have "GGI" instead of "AMI", am I right? If yes then I cannot help you since I've only used 2.x and above for sliding meshes. Nonetheless, this is how I define the AMI pressure BC in 2.1.x and 2.2.x and it works:

AMI1
    {
        type            cyclicAMI;
        value           uniform 0;
    }

Maybe check the tutorials/incompressible/pimpleDyMFoam tutorials for the version you are using. There should be either a mixerVessl or propeller which use AMI or GGI.

Good luck,

A

Thank you very much for your help.
I am using OpenFoam 2.2.1. I wil try following your advive.
