The numerical approximation of the minimum problem: ${min}_{A \subseteq Ω} \tilde{F} (A)$ , is considered, where $\tilde{F} (A) = P_{Ω} (A) + \cos (θ) H^{n - 1} (\partial A \cap \partial Ω) - \int_{A} κ$ . The solution to this problem is a set $A \subseteq Ω \subset R^{n}$ with prescribed mean curvature $κ$ and contact angle $θ$ at the intersection of $\partial A$ with $\partial Ω$ . The functional $\tilde{F}$ is first relaxed with a sequence of nonconvex functionals defined in $H^{1} (Ω)$ which, in turn, are discretized by finite elements. The $Γ$ -convergence of the discrete functionals to $\tilde{F}$ as well as the compactness of any sequence of discrete absolute minimizers are proven.
