3D Navier Stokes Solver

3D Navier Stokes Solver using 5th Order WENO and Upwind scheme written in Julia with RK3 time stepping.

How to use

Input

Please use the input.yaml to change the parameters to run the solver

Params

Flags

• ivis: viscous terms enable/disable 0 or 1
• iflx: pick flux scheme 1 or 2
• ihpc: 0 or 1 (some fixes to run on Headless machines)

Output

Output format used is .vtk files and .pvd file corresponding to the snapshots generated during the run.
