TALK=T;RUN(1,1) DISPLAY 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.
