DOI: 10.1002/fld.4830
Abstract: A novel adaptive algorithm that is based on new hierarchical Fup (HF) basis functions and a control volume formulation is presented. Because of its similarity to the concept of isogeometric analysis (IGA), we refer to… read more here.

DOI: 10.1017/jfm.2018.219
Abstract: The steady speeds of the front of a gravity current and of an internal jump on a two-layer stratification are often sought in terms of the heights of the relatively dense fluid both up- and… read more here.

DOI: 10.1038/s41598-020-61324-4
Abstract: We present a novel velocity based up-winding scheme for the node control volume finite element (NCVFE) method. The NCVFE method solves for the pressure at the vertices of elements and a control volume mesh is… read more here.
