Relevance and Relevance Center
 
Hi,

I've some queries about the relevance features in ANSYS Meshing (AM). There are 3 options for the Relevance Center (RC) of Coarse, Medium and Fine and a numerical range for the Relevance (R) of -100 to 100. As I use CFX by default AM sets RC = Coarse and R = 0. So if I want to globally refine a mesh by a factor, of lets say 1.5, as part of a mesh independence study what would be the correct settings for the RC and R? The User Guides do not explain how these work. Also how do they work when compared to the ICEM Global Element Scale Factor (which simply multiples mesh sizings by a factor e.g. 1.5)?

To me it seems strange to have 2 parameters (RC and R) when a single scaling factor would be more sensible and intuitive.

Of course, the other option is to ignore RC and R and change every sizing manually but is more time consuming.

Thanks.
