Rhale : a 3-d Mmale Code for Unstructured Grids

  title={Rhale : a 3-d Mmale Code for Unstructured Grids},
  author={J. S. Peery and Kent G. Budge and Michael K. Wong and Tim G. Trucano},
This paper describes RHALE, a multi-material arbitrary Lagrangian-Eulerian (MMAL shock physics code. RHALE is the successor to CTH, Sandia’s 3-D Eulerian shock physics and will be capable of solving problems that CTH cannot adequately address. We discuss the Lagrangian solid mechanics capabilities of RHALE, which include arbi mesh connectivity, superior artificial viscosity, and improved material models. We discus MMALE algorithms that have been extended for arbitrary grids in both twoand three… CONTINUE READING
