Following Lozinski et al. (2009) [13], a quadratic time reconstruction is used.Adaptive finite elementsA posteriori error estimatesConvection-diffusionCrank-Nicolson schemeFinite-Element MethodsPosteriori Error EstimatorsAdvection-DiffusionTetrahedral MeshesStokes ProblemsEquationsFlowAn adaptive algorithm for the Crank-Nicolson scheme applied to a time-dependent convection-diffusion problemtext::journal::journal article::research article
