I see a difference in the pattern of mesh generated using STL algorithm in ANSA v16 compared to earlier versions like ANSA v15.1.2.
Can anyone help me in getting the same type of STL mesh using Spacing option which was generated in ANSA v15.1.2 in 16.1.2 ? Thanks for your help in advance. |

Hi there,
The Shell Mesh>STL algorithm changed in ANSA v15.2.0 It may not create as regular mesh patterns as older ANSA versions but it is in fact more accurate than the old algorithm, in the sense that it truly respects the max distortion and feature angle limits set by the user. To achieve this, it may create some local size reductions in the macro. There is no real reason to prefer the old algorithm to my belief. Hope this helps Vangelis |

Is there any way to get the same pattern as in 15.1.2, because that looked good for external aerodynamic meshing.
Thanks alot for replying. Regards, Vignesh Sent from my ZUK Z1 using CFD Online Forum mobile app |

No you cannot achieve the result of v15.1.x as the algorithm has changed.
