Dear colleagues,

I'm trying to mesh a Wigley hull form for hydrodynamic analysis! I have tried both ANSYS Meshing and ICEM to create a tetra/prism mesh for this geometry! however when I try to add a boundary layer on the hull surface using inflation, the mesh quality decrease drastically

here is the hull form which consist of sharp edges at the front, back and bottom:


I have tried to change many parameters and this is the best I could get:

min orthogonal quality: 0.015
max skewness: 0.98

The low quality and skewed elements are within the boundary layer...

Is there any way to get a better mesh?

best wishes
tnx in advance

Just to let you know, I have managed to fix the problem by adding zero-thickness plates at sharp edges! this way the prism layer doesn't need to turn around the hull!

now I get:

min orthogonal quality: 0.105
max skewness: 0.86

Hi,
Thanks for sharing your result, can you please elaborate more about how you treat the sharp angle.
