Abstract
A scheme is presented for the automatic generation of unstructured rectangular meshes suitable for the integration of dynamically adaptive, time dependent Eulerian codes. Our approach generates meshes quite different from those in the existing literature, which are primarily based upon block structured or grid embedding algorithms, and therefore have the inherent disadvantage that they inevitably place fine mesh cells in regions somewhat larger than actually necessary. Our meshes do not suffer this drawback: they possess fine cells only where necessary, and not in blocks extending into regions of relative ‘inactivity.’ Results are given for the particular cases of the initial configurations of rectangular and circular penetrators striking an oblique plate.
