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.
If you require help using this software, or would like to report a possible problem with it on one of our systems, please contact the HPC Help Desk.
