Work within the duration of this award had two major components, improvements to the numerical properties of several of the Uintah components, and enabling the use of those components across a wider range of applications. In the former category, improvements to the Material Point Method (MPM) include better time integration, a more accurate method for transferring particle data to the computational domain and further AMR development. Uintah has been brought to bear on a number of new and interesting physical scenarios such as stage separation in rocket motors, behavior of large-scale ''agent defeat'' devices, blast wave interactions with military vehicles, projectile impact in the human torso, angiogenesis and machining. Several of these new applications have gone on to secure independent funding, but in each case, new capability was added to the to extend Uintah's functionality.
