The control volume approach is used to obtain a finite-difference scheme for a Lagrangian formulation of inviscid incompressible flow using an irregular triangular mesh. The method permits grid reconnections and allows local vertex addition and deletion. Algorithms are presented which conserve divergence vorticity, mass, momentum and energy even during grid restructuring. Examples are taken from simulations of shear flow and flow over a hydrofoil in which the restructuring algorithms are crucial. Although the structure of the code is highly scalar, techniques are outlined for producing efficient code even for the new vector computers. Author
