Dear all,
I am attempting to extend the edge of a structure by using the 'sweep surface' tool and selecting the curves of the edges. However, I find the swept surface is not always attached to the original surface and doesn't always follow the curves perfectly. Is there a way to fix this? Thank you very much. |

Hi,
Thanks so much for your offer to help. I was using ICEM CFD and I found that although there were gaps in the model, after meshing in ICEM CFD there were no visible gaps in the mesh. Does this suggest that I don't need to worry about the gaps in the model? Thanks a lot. |

Hi MDN,
the graphical view is only a representation of the actual model. The graphics are triangulated and only resolves geometries until a given limit. You can decrease the triangulation tolerance to resolve finer structures at the cost of more workload on your graphics card. Have a look into the options in the general tab if i remember correctly, there you should find triangulation tolerance. If this does not work, try decreasing the topology tolerance, i might mixed those two quantites up, and cant check my suggestion. Somewhat off-topic: This one is a nice read for more abstract perspective: https://blog.pointwise.com/2017/11/2...ry-is-inexact/ In contrast to CAD, ICEM (or most mesh generators) needs mathematically correctly intersected geometries in order to determine what's inside and outside. Best, Sebastian |

Hi Sebastian,
Thank you very much for your explanation. I found the link very helpful too and I now understand why the gap exists! Thanks again! Best regards, M |
