I have imported a 2D mesh from Gambit with the argument -writeZones. I now want to initialize a value in the specified Zone using a clone of the dambreak case. How do I refer to the zone (as when setting a porous zone)instead of a box as they do in the damBreak case? My zone is specified under polymesh in cellZones and faceZones.


I have tried to replace the 'boxToCell' with the zone name but without progress. Can anyone tell my how to write the setFieldsDict?

defaultFieldValues
(
volScalarFieldValue gamma 0
volVectorFieldValue U (0 0 0)
);

regions
(
boxToCell
{
box (0 0 -1) (0.1461 0.292 1);

fieldValues
(
volScalarFieldValue gamma 1
);
}
);

Use the setFields utility just like you use any other utility.

In the console when you type setFields you will be able to see the format.

$ setFields /user/OpenFoam/run/tutorial damBreak

Then check the gamma in paraFoam.

Hi
I have run the setFields and they suggest several commands:

(
pointToCell
boxToCell
zoneToPoint
surfaceToCell
nearestToCell
zoneToCell
cellToFace
pointToFace
normalToFace
boxToFace
rotatedBoxToCell
fieldToCell
cellToPoint
zoneToFace
nbrToCell
patchToFace
labelToCell
pointToPoint
faceToCell
boxToPoint
labelToPoint
boundaryToFace
faceToPoint
labelToFace
shapeToCell
faceToFace
cellToCell
surfaceToPoint
)

Which one shall i use and how do I edit my setFieldsDict? The Zone-name is 'Mesa' and I have tried the following without success:

defaultFieldValues
(
volScalarFieldValue gamma 0
volVectorFieldValue U (0 0 0)
);

regions
(
faceToCell

Mesa

{

fieldValues
(
volScalarFieldValue gamma 1
);
}
);

Dear Christofer,

did you manage to solve the problem??
I am very interested in the outgoing of your application!

Here is the link to my posted problem, maybe you can see the relation and give me a hint:
make Box by use of surrounding faces

Currently I am trying to set volume zones within my mesher Icem (Ansys) to write them in with -writeZones during the transfer to OF.
How can I relate to them afterwards and how can I set Alpha1 to 1 in my desired volume zone??

Thank you very much for helping!
Greetings, Markus.
