Hi,
I went through the paper titled "Numerical Solution of the Euler Equations by Finite Volume Methods Using Runge-Kutta Time-Stepping Schemes" which has been cited in the AIAA SU2 paper for implementation of the JST scheme.

I wish to carry out certain modifications to this scheme.

The paper mentions that:
"Each quantity such as u 1 or (ρu) 1 is evaluated as the average of
the values in the cells on the two sides of the face,
Equation>(2.7) (ρu)1 =(1/2)(ρu) i,j + (1/2) (ρu) i+1,j "

I am unable to locate to the exact function that carries out this operation. Can you please help me with the same?

Also, which is the function associated with Equation (3.10) of the same paper?

Thank You.
