<p>How to access yplus values at all cells as my UDF needs to return different values based on different range of yplus. ANSYS Fluent only provide Wall yplus in the cell macros, which has first cell y plus next to the wall. How to map y plus distributed values across the domain?<\/p><p>yplus = ustar * y \/ nu where ustar needs wall shear stress value at y = 0<\/p><p>Let’s say even if I am trying to create my own UDMI or UDS for yplus, it is essential to access the near wall (y=0) values for calculating the yplus, which I am not sure how to handle it?<\/p><p>Any information or help regarding this would be valuable.<\/p><\/p>\n","protected":false},"template":"","class_list":["post-395286","topic","type-topic","status-publish","hentry","topic-tag-udsudm","topic-tag-fluent","topic-tag-yplus"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
