A new efficient approach for 3D hydrodynamics simulation
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
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!
