CTH on Centennial


CTH is a multi-material, large deformation, strong shock wave, solid mechanics code developed at Sandia National Laboratories. CTH has models for multi-phase, elastic viscoplastic, porous and explosive materials. Three-dimensional rectangular meshes; two-dimensional rectangular, and cylindrical meshes; and one-dimensional rectilinear, cylindrical, and spherical meshes are available. It uses second-order accurate numerical methods to reduce dispersion and dissipation and produce accurate, efficient results.


CTH is export-controlled software. Access is limited to U.S. Citizens. Contact the ARL MSRC Helpdesk for information on how to access CTH.
