adjointShapeOptimizationFoam

Hello everyone!

I am using OpenFOAM 2112, trying to assess the applicability of the adjointShapeOptimizationFoam solver for optimizing internal flows.

Is it possible to define "non-design" regions? i.e. regions where alpha must be 0.

Also, is it possible to model porous regions (apart from the implemented alpha) to model other resistances? I am guessing this will require developing a custom solver?

Thanks!

regarding making "non-design" zones, I can see there is a template function "zeroCells", defined in adjointShapeOptimizationFoam.C to make variables zero.

Code:

void zeroCells 
(
    GeometricField<Type, fvPatchField, volMesh>& vf,
    const labelList& cells
)
{
    forAll(cells, i)
    {
        vf[cells[i]] = Zero;
    }
}

This function is used in the SIMPLE loop to make the inlet cells zero alpha:

Code:

zeroCells(alpha, inletCells);

I guess this function could also be used to make "non-design areas"? anyone has tried?
