    Hello Developers,
    How do I extract the force values stored in the lattice for the Poiseuille2d case example?

    Thank you.

    Yours sincerely,

    Abhijeet

    You can get the external force vector for a given spatial cell location e.g. via

    
Cell<T,DESCRIPTOR> cell = superLattice.getBlockLattice(iC).get(iX,iY,iZ);
Vector<T,3> force = cell.template getField<descriptors::FORCE>();
