problem with void fill and creating inner volume

[Anonymous]

Hi

Im doing my Master thesis in product development and need some help with simulation cfd 2017

We have done "revered engineering" on a water-vaccumcleaner. So we built the model in creo and when we import it to simulation cfd 2017 it will not find the inner volume (have blocked inlet and outlet), And tried without blocking and i used Void fill but i get this massage: ((((an insufficient number of surfaces were defined to yield additional parts)))))

I cant find where the leak is...

Before i have done a basic flow analysis so i have used the program a little before, but i cant find out why it will not make the inner volume and not even when i open inlet and outlet and make a void surface for inlet and outlet instead, still void fill wont work....Im looking in my creo cad model, but i dont see any leaks/holes/cracks

We dont have the support in autodesk cfd here and i dont want to try in Ansys fluids.

Its 3 parts merged into one part! Top, mid and bottom! I can se some edges where top and bottom part meet, but it should still be no leak. its no openings....

would appreciate all help we can get

best regards 

Sam

Hi @Anonymous,

Thanks for reaching out on the forums! This issue shouldn't be too hard to resolve. Here is a great post that details a pretty creative solution. Give this a try and see if you can resolve the problem. If you are still facing problems, please upload your CAD geometry and I can take a look at it.

Good Luck!

Thanks,
