Version 1.0

Cholla is a 3D hydrodynamics code designed to quickly compute problems on very large grids. Features included in the public release of Cholla, version 1.0 include:

  • 1, 2, and 3D hydrodynamics
  • Exact and Roe Riemann solvers (with HLL fallback)
  • Piecewise constant, linear, and parabolic interface reconstruction
  • Traditional, CTU, and Van Leer (predictor-corrector) integrators
  • Dual energy formalism
  • H correction to fix carbuncle instabilities
  • Optically thin radiative cooling

Cholla includes a variety of test problems used to confirm the performance and accuracy of the code.
