Abstract

A novel three-dimensional adaptive meshing algorithm is presented and applied to finite-element simulations of multiphase fluid flows. A three- dimensional domain enclosing another phase is discretized by an unstruc- tured mesh of tetrahedra constructed from a triangulated surface of the phase boundaries. Complete remeshing is performed after each time step. The boundary mesh is reconstructed using an existing algorithm employ- ing element addition/subtraction, edge swapping based on Delaunay trian- gulation and spring-like dynamical relaxation. The volume m
