Adaptive Mesh Generation for the Modeling of Bat Flight

Summary	A wireframe model of a flying bat. The modeling is performed by constructing a large box containing the bat. The bat inside a box. A tetrahedral mesh is constructed in the interior of the box, such that the face ahead of the bat is considered the inflow, the face behind is the outflow, and the other faces are paired for the use of periodic boundary conditions. The mesh is used as input to the spectral/hp element solver Nektar which solves the incompressible Navier-Stokes equations in arbitrary Lagrangian-Eulerian formulation. A nonuniform mesh of the bat inside a box.
