zone-surface: cannot create surface from sliding interface zone. Creating empty surfa
 

Hello All

I am having "zone-surface: cannot create surface from sliding interface zone.
Creating empty surface" in Fluent. How can I get rid of this interface. My geometry is very simple. A pipe tee connected to a straight run pipe. I never had this issue before in the same geometry but now it is coming in every attempt. Can someone advise how I may get rid of this interface. If I delete contacts in Ansys Meshing, will it make much difference. I have to use Openfoam to solve but I have created geometry in designmodeler as openfoam is not good to make this type of geometry and before importing in openfoam, i must get rid of it.

I shall be very grateful.

Regards
