How to fix this?

Wilson

Hi, I am interested in monitoring the pressure contours across the condenser, where in the fans sucks the air from the atmosphere over the surface of the tubes in condenser . I made a sufficient length both before the condenser and after the fan.

Boundary conditions are

1.Before the condensor â€" Pressure Inlet BC (which is open to atmosphere) 2.After the condensor â€" Intake Fan 3.After the fan to sufficient length â€" Pressure outlet.

This is the way I applied the BC to solve this problem, when I tried for a Grid check , I got a warning in FLUENT stating that - GRID CHECK FAILED and error is Pressure inlet zone has two adjacent cell zones.

My question is Whether the applied BC's are right? How to fix this error and elaborate me why I am getting this error?

Thanks Wilson
