The walls repel the hard spheres (of diameter $\\sigma$) with a Weeks-Chandler-Andersen (WCA) potential $V_{WCA}(z) = 4 \\epsilon [(\\sigma_w/z)^{12}-(\\sigma_w/z)^6 + 1/4]$, with range $\\sigma_w = \\sigma/2$. We vary the strength $\\epsilon$ over a wide range and the case of simple hard walls is also treated for comparison.
