I have a problem with ANSYS Discovery. It was suggested among my contacts that you could help. Can you help if you are available?
There are many cylinders in my geometry. Water is passing through these cylinders. I do not want to enter velocity/mass flow and temperature for each cylinder. Instead, can I select each inlet surface and define them with a single input?How can I do this? When I select each surface and define the properties for inlet from the ''flow'' option, I get the warning below. I can't figure out how to fix this.

Hi Mehmet, 

Yes, you can select multiple inlets surfaces and apply a single input. Press Ctrl key while manually selecting multiple faces or use Power Selection. 

Please check that you are selecting correct faces for applying the inlet condition. You can right click hide the other geometries to easily select faces.

I selected 50 surfaces from the power selection section. I had to enter the inlet with the same value one by one. Finally, the solve option opened. Unfortunately, I could not define 50 surfaces at once with a single inlet value.

Are you applying the boundary condition for 2 different materials with one inlet? 

Can you share more details/images to understand the flow in your case? Do these cylindrical fluid region merge ahead?

[mehmet.yoladi]

The materials are the same and the output does not meet in one place. The image is attached.

Is it necessary for the flow to converge at a point?

I think it would be more appropriate to apply it to selected surfaces at once with a single outlet as a ''pressure outlet''.

I can do these operations in fluent. But it doesn't work here.

Hi Mehmet,

Thanks for sharing this image. These all cylinders have individual flow paths with no single outlet. 

Its not possible to apply single input boundary condition on such surfaces. 

Thanks and Regards
