setFields not working
 
Hi, i am simulating a water channel and got a problem with setFields.

when i run setfields, it doesn't report any mistakes.

Create time
Create mesh for time = 0
Reading setFieldsDict
Setting field default values
Setting internal values of volScalarField alpha1

Setting field region values
Adding cells with center within box (-100 -100 -100) (100 100 100)
Setting internal values of volScalarField alpha1

End


however, it doesn't write any cel data in alpha1, it only changes the internalField value from 0 to 1

this is my setFieldsDict

defaultFieldValues
(
volScalarFieldValue alpha1 0
);

regions
(
boxToCell
{
box (-100 -100 -100) (100 100 100);
fieldValues
(
volScalarFieldValue alpha1 1
);
}
);



this is my alpha1 file before running setFields

dimensions [0 0 0 0 0 0 0];
my
internalField uniform 0;

boundaryField
{
wall
{
type zeroGradient;
}

pumpe1
{
type inletOutlet;
inletValue uniform 1;
value uniform 1;
}
pumpe2
{
type inletOutlet;
inletValue uniform 1;
value uniform 1;
}
pumpe3
{
type inletOutlet;
inletValue uniform 1;
value uniform 1;
}
pumpe4
{
type inletOutlet;
inletValue uniform 1;
value uniform 1;
}
kanal1
{
type inletOutlet;
inletValue uniform 1;
value uniform 1;
}
kanal2
{
type inletOutlet;
inletValue uniform 1;
value uniform 1;
}
kanal3
{
type inletOutlet;
inletValue uniform 1;
value uniform 1;
}
kanalrest
{
type inletOutlet;
inletValue uniform 1;
value uniform 1;
}


atmosphere
{
type inletOutlet;
inletValue uniform 0;
value uniform 0;
}

}

it can't be something that difficult, it has to be a mistake i made! i have a similar test case working!

thank you very much for your help!

Is your entire domain inside your setFields box?

i tried different boxes for setFields, none were working. now i just tried to define the corners of the boxes the other way arround and suddenly it worked! no idea why it shouldnt work the other way arround!

thank you
