Change BC interior to wall after calculation

  Hello,
  Is it possible to change an Interior zone to Wall after a solution is calculated without affecting the flow? Since the default shear condition for Wall zones is "No Slip", when I change a certain zone from Interior to Wall the flow at the faces is re-initialized as 0. Is there a way to prevent fluent from changing the obtained solution, even if the BC change?
  Thanks

  If you're running Fluent outside of Workbench make the change and then carry on doing whatever you were doing. The reported speed on the wall will be zero, the neighbouring cell value should be unchanged. If you explain why you want to do this we may be able to give you a better solution.
