Based on recent mathematical advances, BhT provides a collection of M-Files for design, simulation and analysis of articulated bodies' motions in fluid. More widely, BhT allows also to perform easily any kind of numeric experiments about the motion of solids in fluids (simulations of so-called...

A Kirchhoff elliptic vortex is a 2D elliptical region (or d-deDUpatchd-deDt) of uniform vorticity embedded in an inviscid, incompressible and irrotational fluid. G. Kirchhoff showed that these are exact solutions to the nonlinear Euler equations in 1876.Subsequently, A. E. H. Love analyzed the...

Five scripts that demonstrate some aspects of the dynamics of rotating reference frames:1) rotation.m shows a very simple 3-d trajectory from inertial and rotating reference frames.2) Coriolis.m simulates a 2-d trajectory in a rotating frame that omits the centrifugal force. This allows several...
