An 'inviscid' boundary layer! This is still a bug (Part 3)
Go to the first part: An 'inviscid' boundary layer! Is this a bug?! (Part 1) Approximately a year ago, I published the initial parts of a series detailing a significant visualization anomaly encountered within the Results module of ANSYS Workbench. I recently tested the newest ANSYS Student version (2025 R2) with the same 2D test case, and unfortunately, the issue persists despite having been reported in the official forum: a modeled boundary layer (BL) appears in the visualization for an inviscid flow simulation (over both an airfoil and a 3D wing; see Fig. 1). It is crucial to emphasize that this visual error does not appear in the ANSYS Fluent solver module. Since the solver correctly recognizes the inviscid condition (μ=0), it does not impose a no-slip condition at the wall, and thus, no boundary layer is formed in the flow solution itself. As those with a fundamental knowledge of fluid dynamics understand this is not a personal interpretation error, I believe this bug ...
