"Invalid Contacts" Flow simulation

Hello 

I am a beginner on Solidworks, I have to carry out an aerodynamic study on a solar prototype on Solidworks. 

When I click on Run to start the calculations, an error message appears " There is no fluid volume in the project. Please check geometry or boundary conditions." 

I don't know how to proceed, thank you for helping me! 

Have a nice day.

Hello

It could be that your geometry is "defective", can you try to run the "Check" and/or "Geometry Analysis" tools  in the "Evaluate" tab?

Thank you for your answer, 

I launched the "Check Geometry" tool, here is the result 

I think there is a link with invalid contacts...

Hello

Have you thought about plugging the orifices, 

May strength be with you.

I didn't know that I had to plug the orifices. 

I'll keep you posted. 

Thank you

Edict: 

I have tubes in the assembly and the tool tells me that they are causing problems for the aerodynamic simulation

After adding material, the error message still appears on these tubes

do the tutorial about Flow simulation.

You'll understand that it's not as easy to use as it sounds!

you need a closed volume, in which you define surfaces through which a flow arrives and/or leaves...

I succeeded, thank you all!
