An application of The Method of Manufactured Solutions into a Spalart Allmaras equation code

Based on the Method of Manufactured Solutions, a finite volume code for the solution of an equivalent Spalart-Allmaras equation (S-A) received code verification. All operators in the S-A equation received coordinates exchange for the curvilinear coordinate system. Then, the diffusive terms were approximated by the CDS-2 method while the advective ones by the UDS method. Succeeding the creation of the Manufactured Solution, the resulting linear system was solved iteratively by the MSI method. After a grid refinement study, the effective order of the computational solution for the finest grid converged to the minor asymptotic order of truncation error value between CDS-2 and UDS methods. This process proves that the code is verified and suitable for CFD applications.
