This example uses the guided workflow for watertight geometry meshing because it is appropriate for geometries that can have no imperfections, such as gaps and leakages. **Workflow tasks** The Modeling External Compressible Flow Using the Meshing Workflow guides you through these tasks: - Creation of capsule mesh using Watertight Geometry workflow. - Model compressible flow (using the ideal gas law for density). - Set boundary conditions for external aerodynamics. - Use the k-w SST turbulence model. - Calculate a solution using the pressure-based coupled solver with global time step selected for the pseudo time method. - Check the near-wall mesh resolution by plotting the distribution of . **Problem description** The problem considers the flow around a wing at an angle of attack a=3.06° and a free stream Mach number of 0.8395 (M=0.8395). The flow is transonic, and has a shock near the mid-chord (x/c≃0.20) on the upper (suction) side. The wing has a mean aerodynamic chord length of 0.64607 m, a span of 1.1963 m, an aspect ratio of 3.8, and a taper ratio of 0.562. ..
