Help in UDF in Blending Function F1 of SST kw

unred486 · June 23, 2016, 12:50

Hello all,

I am trying to write a udf code for blending function f1 of SST kw. However, it seems that variable y which is a distance from the nearest wall is abit hard to define. Is there any way to define this variable? or is there maybe a way to extract the value of blending function to udf?

Thank you for your help in advance!

Han

Hi,

How did you fix it? Did you use C_WALL_DIST(c,t)? I get segmentation error whenever I use that.
What version of Fluent are you using?
