    The Q1 presents a test case for viscous flow through
    a highly distorted mesh, with or without a body force
    representing a porous medium.

    It allows the behaviour of the GCV, CCM and standard
    staggered solvers to be compared.

    In all cases, the vector field should show completely
    uniform flow.

    If the body force is not included, the pressure should
    be uniform and zero, as there are no wall boundaries.

    If they are included, there should be a uniform pressure
    gradient in the X direction.
