Hi Foamers:

After run the tutorial of pimpleDyMFoam's mixerVesselAMI2D.I got the p result.and I want to make a conparision with interDyMFoam, so I set the alpha's internal field is uniform. and g is 0. and I think the result of this two solvers should be the same.but I got a unsatisfactory result. the image is attached.

I think if the internal field of alpha is the uniform. the interDyMFoam's result should be the same with pimpleDyMFoam.rite?

Anyone can give me a hint what is happening to this?



alpha:
Code:
dimensions      [0 0 0 0 0 0 0];

internalField   uniform 1;

boundaryField
{
    rotor
    {
        type            zeroGradient;
    }
    stator
    {
        type            zeroGradient;
    }
    AMI1
    {
        type            cyclicAMI;
        value           $internalField;

    }
    
    AMI2
    {
        type            cyclicAMI;
        value           $internalField;

    }
    front
    {
        type            empty;
    }
    back
    {
        type            empty;
    }
}
p-rgh
Code:
dimensions      [1 -1 -2 0 0 0 0];

internalField   uniform 0;

boundaryField
{
    rotor
    {
        type            zeroGradient;
    }

    stator
    {
        type            zeroGradient;
    }
AMI1
    {
        type            cyclicAMI;
        value           $internalField;
    }

    AMI2
    {
        type            cyclicAMI;
        value           $internalField;
    }

    front
    {
        type            empty;
    }

    back
    {
        type            empty;
    }
}
other things in constant dictionary are totally the same with pimpleDyMFOAM's mixerVesselAMI2D.
