Meshing error

[SBlock]

Hi choirul,

in regards to the mesh setup.

Please consider further refining your mesh. As you can see in the image below, the leading edge of your wing only has a resolution of 2 cells. thus the curvature can not be really captured.

here are a few tips for mesh generation.
#1 Please consider using the standard meshing algorhym as this is more robust for complex shapes.
#2 Pleas us refinement regions and surface refinements. You can find out more about refinement regions here:

Standard Mesher | Meshing for CAE | Documentation | SimScale

#3 please consider enlarging the flow region. an example of the rough dimensions can be seen here:

Please also find my tips on how to create a good mesh for external vehicle / wings here:

Poor mesh quality for 15M cell mesh

Hi, so I’ve decided to do a quick n dirty CFD run on a F1 style wing I designed in NX. When it came to geometry and mesh prep, I followed this tutorial (although went for a slightly bigger wind tunnel and refinement box size given the geometry difference) I uploaded my geometry as a native NX part file, consisting of ONE SOLID BODY (ie, designed half the wing, mirrored both profiles and endplate about the XZ plane, and then used the unite command on the original geometry and the mirror). Th…
