Computational Aerodynamics Questions & Answers  


The userdefined constant $\epsilon$ is included to prevent a division by zero. Set it to a very small value. As for $\gamma_0$ and $\gamma_1$, they are fixed constants: don't change them.






OK, will look into this now.




You don't necessarily need to express $\phi$ as a function of $U$ to determine $\partial \phi/\partial U$ in the same way as you don't need to express $F$ as a function of $U$ to obtain $\partial F/\partial U$.




Use a 1D extrapolation polynomial. 2D is too time consuming to compute.




No, $A$ is a $2 \times 2$ matrix determined from an average state function of $Z_L$ and $Z_R$.
