WebJan 26, 2010 · This study models the atmospheric response to such early-time energy coupling using the CTH hydrocode written at Sandia National Laboratories. Results show that the surface surrounding a 10 km diameter crater (6 km “apparent” diameter) on Mars will be subjected to intense winds (˜200 m/s) and extreme atmospheric temperatures. WebNov 1, 1997 · The CTH hydrocode simulation results provided the much needed information to help determine the critical particle sizes required to sever the tether. The M/OD particle sizes required to sever the tether were estimated to be less than 0.1 cm in diameter from these studies, and these size particles are more abundant in low-Earth …

WebCTH hydrocode simulations require high resolution; on the order of 80 cells per millime-ter. We found considerable numerical oscillation around the material interface of explosive products and air at lower resolutions. This means 160,000 cells for a one-dimension(1-D), 2 meter domain in spherical coordinates. WebRadiation Transport Diffusion (CTH) hydrocode; verify the algorithm; and conduct preliminary studies to assess this novel framework. The final product is an improved predictive capability implemented into the CTH hydrocode developed by Sandia National Laboratories to allow for
