siw will become famous soon enough

In ANSYS Meshing (AM) there is an option: Outline > Mesh > Sizing > Smoothing. There are 3 choices for the smoothing: Low, Medium and High.

Since alot of the AM technology has been developed from ICEM CFD how does the AM smoothing feature compare? In ICEM you can choose what element types, smoothing level, smoothing algorithm (Laplace or not) and so on. Whereas, in AM smoothing is limited those 3 names.

Does anyone know what AM is doing in the smoothing (the User Guide does not say) compared to ICEM? I've have tried all 3 and can see an improvement in a mesh but it would be good to get an idea of what's going on, especially when ICEM gives so many choices.

I am not directly involved with that technology in ANSYS Meshing, but I can tell you that it is not an ICEM CFD algorithm...

There are actual numbers behind the scenes, I forget what they are, but setting those simplified settings such as "medium" sets a bunch of smoother settings and off it goes.

They meant it to be simple, but instead it comes across as mysterious. I think there are plans to be more transparent in a future version.

I think they have plans to fix it in future versions, but in the mean time, I will put in a request for better doc.
Far and siw like this.
