Implementation of the Thin-Film Equation on Prestructured, Switchable Substrates Using the oomph-lib Library
This tutorial shows how a switchable prestructured substrate for a one and two-dimensional thin-film model can be implemented using the oomph-lib library. In particular, the case of a moving step wettability profile (see Grawitter et al.) was considered.
Within this tutorial, the code necessary to reproduce all the simulations and analysis is explained. Table 1 in section 1.4 gives an overview of the necessary files. In the accompanying source code, different wettability prestructures and switching patterns are already implemented, which can be used with minor adaptions to the supplied source code.
