Boundary layer mesh generation for viscous flow simulations

Viscous ow problems exhibit boundary layers and free shear layers in which the solution gradients, normal and tangential to the ow, di er by orders of magnitude. The generalized advancing layers method is presented here as a method of generating meshes suitable for capturing such ows. The method includes several new technical advances allowing it to mesh complex geometric domains that cannot be handled by other techniques. It is currently being used for simulations in the automotive industry
