CUDA-DNS

cuda-solver for 3D COMPRESSIBLE NAVIER-STOKES EQUATIONS

features:

  • rk3 or rk4 for time stepping
  • possible to choose between 2nd, 4th, 6th or 8th order spatial discretization
  • shared memory usage for fast derivation
  • cuda dynamic parallelism to ensure correct memory access in x- y- and z- derivatives
  • flux formulation to solve the conservative full split form of the advective terms

Text cases:

substitute the globals.h to the globals.h in the src folder before compilation to run these cases
