Influence of different resolutions: Results for \(\varepsilon _{11}\) compared to a sharp-interface solution at \(t=20\,\hbox {s}\). Three resolutions of \(\Delta x =\left\{ 1.00, 0.50, 0.25\right\} \,\upmu \hbox {m}\) are plotted along a x with \(y = 49.5\,\upmu \hbox {m}\) and b the grid points in the interface (i.e. the interface is entered from the left at interface grid point 0 and left towards the right at interface grid point 12)
