Dear FOAMERS;

I am working with interFOAM and would like to have a case as shown in the figure.

I would like to specify an alternating phase at the left end of the domain. I tried using something like '&&' to initialize multiple patch values in setFieldsDict but it could read and set only one value out of a group of values.

I am not sure if this could be done with setFields and the alternate is using swak4FOAM.
Could anyone give a hint how could i do this in swak4Foam as i see no thread related to this setFields interFoam concept used for initialization of alpha values.

Thanks;

Anyone with an idea how to define this please..!!

hello Saideep,

did you look at damBreak4phase. I think there is done what you want.

hope this helps

Hi Wouter;

Thanks a lot!! Yes i checked the damBreak4Phase and it is quite straight forward to use that. I was rather exploring the swak4Foam and other groovyBC's for assigning such b.c's for alpha.

However just to complete the thread and maybe someone can find this useful:
setFieldsDict file:

defaultFieldValues
(
    volScalarFieldValue alpha.air 1
    volScalarFieldValue alpha.water 0

);

regions
(
    boxToCell
    {
        box (0 0 0) (10e-6 33e-6 50e-6);
        fieldValues
        (
            volScalarFieldValue alpha.water 1 
            volScalarFieldValue alpha.air 0 
        );
    }

    boxToCell
    {
        box (0 33e-6 0) (10e-6 66e-6 50e-6);
        fieldValues
        (
            volScalarFieldValue alpha.air 1 
            volScalarFieldValue alpha.water 0 
        );
    }

    boxToCell
    {
        box (0 66e-6 0) (10e-6 100e-6 50e-6);
        fieldValues
        (
            volScalarFieldValue alpha.water 1 
            volScalarFieldValue alpha.air 0 
        );
    }

    boxToCell
    {
        box (0 100e-6 0) (10e-6 133e-6 50e-6);
        fieldValues
        (
            volScalarFieldValue alpha.water 0 
            volScalarFieldValue alpha.air 1 
        );
    }

    boxToCell
    {
        box (0 133e-6 0) (10e-6 166e-6 50e-6);
        fieldValues
        (
            volScalarFieldValue alpha.air 0 
            volScalarFieldValue alpha.water 1 
        );
    }

    boxToCell
    {
        box (0 166e-6 0) (10e-6 200e-6 50e-6);
        fieldValues
        (
            volScalarFieldValue alpha.water 0 
            volScalarFieldValue alpha.air 1 
        );
    }
);

and final image in fig1. Though this is a simple case i wanted to have this sort of setFields for a more complex structure and started with this as an initial step.

Thanks;
Saideep
