hey everyone!

I am currently implementing the boundary conditions for my solver, and I have a question for you.

I have been reading this article (Inflow/Outflow Boundary Conditions with Application to FUN3D), which is available online at this address.,d.dmQ

I have already found some typos in it, but I would like to have your opinion on that one.

If you go page 8, they defined the Riemann characteristics R+ = -Ui - 2ci/(gamma-1) in Eq. 37. Shouldn't it be R+ = -Ui + 2ci/(gamma-1) instead? The same thing happens in Eq. 39, so that their b coefficient in Eq. 43 is 2R+ instead of -2R+.

Is that actually a mistake in the article, or did I miss something?

Thank you for your help!
