Ansys Fluent & Transient boundary problem [pictures/files attached]
 
1 Attachment(s)
Hello,

I tried to define a transient velocity input for fluent using both Profiles & Tabular data method described in Ansys 14.5 documentation, the profiles are imported correctly and even I can see fluent is plotting them well in Plots->Profile data, but in the results, when I plot the velocity input for midpoint, a linear profile is plotted instead!

I've attached the .prof .ttab files.

Here is what I define at inlet :

Here is what fluent gives me in results at inlet instead :
