- •
We adapt a characteristic boundary condition scheme for compressible MHD.
- •
The scheme correctly converges to the gasdynamic system with B=0.
- •
We apply the scheme to the Brio–Wu shock tube as a case study.
- •
Open end and solid wall boundaries are analyzed.
- •
Extrapolated and characteristic boundary schemes were compared.
