A new efficient approach for 3D hydrodynamics simulation
Jacob I. Waltz, USDOE National Nuclear Security Administration (NNSA) · 2015
LANL’s CHICOMA code solves the compressible hydrodynamic equations on moving tetrahedral grids. Hydrodynamic equations can be solved in Lagrangian, Eulerian, and Arbitrary Lagrangian-Eulerian reference frames. The equations are solved using a finite element method coupled to approximate Riemann solvers. The methods have been extensively verified against relevant analytical solutions. CHICOMA is 103-104 times faster than current production codes for the same level of accuracy!
