MaranStable: A linear stability solver for multiphase flows in canonical geometries

MaranStable is a software to perform three-dimensional linear stability analyses of steady two-dimensional non-isothermal multiphase flows in canonical geometries. Different approximations to the Navier-Stokes equations can be selected, which are discretized by finite volumes on a staggered grid. The stability of the basic flow, obtained by Newton-Raphson iteration, is computed by solving the linearized three-dimensional perturbation equations using normal modes. All calculations are based on MATLAB and make extensive use of the already parallelized backslash and eigs operators, and the graphical user interface eases the access to MaranStable.& COPY; 2023 The Author(s).
