“…In [18], a fully decoupled, linear and positivity preserving finite-element method for solving the chemotaxis-Stokes equations has been recently developed for a similar setup. In [12], the chemotaxis-fluid model without the discontinuous oxygen cut-off function r(c) has been considered, for which a finite-element method has been constructed, optimal error estimates have been established, and convergence towards regular solutions has been proved. In [19,20], a generalized chemotaxis-diffusion-convection model, which includes the dynamic free surface and appropriate boundary conditions, has been proposed together with a numerical method, which uses a time dependent grid and incorporates surface tension and a dynamic contact line.…”
