Euler-based parallel Newton- K r ylov-Schur ow solver
 
I am final year student and taken up project of cfd analysis of blended body wing aircraft. I have found AIAA journal on this and they are using "Euler-based parallel Newton- Krylov-Schur ow solver" to solve the flow at M=.85 Now I want to know if there is equivalent model in fluent to solve the flow??

Just use the inviscid solver (i.e. to solve the Euler equations). Newton-Krylov-Schur just refers to how the system of equations is linearized and solved, which isn't really important if you are just looking for a solution. Fluent uses an algebraic multigrid method to solve its linear systems, not a Krylov method. Not sure if a Krylov option exists somewhere, but it is not the default.
