  Hi I want to solve K Omega SST model that integrates upto the wall with the boundary conditions for wall like this.
  I do not like to use any kind of wall function to predict the value at first cell centre from algebric expression. But Fluent documentation telling K-Omega SST implementation uses wall function
  How to disable the same ?
  Cheers

  There is no possibility for a user-specified BC for omega in Fluent.

  This is the value of omega supposed to be at boundary when no wall functions are used. Wall fnctions often artificially creates turbulence. So integrating the omega upto wall gives good result.
  Not sure, why Ansys does not provide any option to disable the wall functions.
