Steve Guest Posts: n/a	Hi, When setting a velocity profile that contains zero values on an inlet plane I run into problems with tke and epsilion profiles on that same plane. The tke and epsilon profiles are also set using a UDF, however for the regions where the velocity is set to zero, the values of tke and epsilon do not agree with the set values in the UDF. "Banding" occurs where I get multiple values along the inlet plane. Since I set these profiles with a UDF on the whole plane, I do not understand why the values should change. Have you seen this before? Is there a fix? Thanks for your time! Steve
