default riemann
How the farfield state is imposed.
Options
| Value | What it does |
|---|---|
| riemann default | Uses Riemann invariants for a non-reflecting inflow with a pressure outflow. |
| pressure | Uses a pressure boundary condition for both inflow (downstream pressure) and outflow (user-specified pressure). |
| supersonic | Uses upstream conditions for both inflow and outflow. |
| preconditioned | Imposes the reference condition as a supersonic inflow on every face, whatever the local flow direction. |
