-In all figures, we have applied a mask to only show the original field, not -the one extended by zero: for example, to plot the pressure, we have selected -that part of the domain where the magnitude of the velocity is greater than -$10^{-7}$. - The plots are easily interpreted: as the flow drives down on the left side and -up on the right side of the upright part of the solid, it produces a shear -force that pulls the left side down and the right side up. An additional part -force comes from the pressure, which bears down on the left side of the top -and pulls up on the right side. Both forces yield a net torque on the solid -that bends it to the left, as confirmed by the plot of the displacement -vectors. +up on the right side of the upright part of the solid, it produces a +pressure that is high on the left and low on the right, and these +forces bend the vertical part of the solid to the right.
