WebAbstract. CTH is a family of codes developed at Sandia National Laboratories for modelling complex multi-dimensional, multi-material problems that are characterized by large deformations and/or strong shocks. A two-step, second-order accurate Eulerian solution algorithm is used to solve the mass, momentum, and energy conservation equations. Webstrong shock, large deformation problems. CTH simulations yield the properties of the debris immediately after impact, including velocity, temperature, phase, material
