CFD Fluent Solution not initializing

[Lumko]

Good day, 

I want to simulate multiphase flows that is gravity-fed at the inlet and lifted from the sump by a submersible pump unsing Fluent.  

However, my solution is refusing to initialise and it gives the following error:

Unassigned interface zones found. Flow is not initialized.

WARNING: Unassigned interface zone detected for interface discharge-pipe-wall-interface

WARNING: Unassigned interface zone detected for interface discharge-pipe-wall-interface.1

WARNING: Unassigned interface zone detected for interface inlet-pipe-wall-interface

This is a SOS, please help.

kind regards,

Lumko

Hi, create mesh interface using Domain > Interfaces > Mesh. Then, select the boundaries that make up the interfaces and click Create.
