I had to import a deformed geometry into simscale and run an incompressible CFD sim in simscale. I tried really hard to clean up my geometry and still there seems to an error which i can’t and even simscale can’t figure out 
Please can someone help?
Thanking you.

Hello,
In short, there are a number of small gaps preventing the operation from completing.
I’d recommend that you try to combine all parts together before importing to SimScale (your software will likely complain about issues) - then it’s just a matter of cleaning the gaps up. For example, below you can see Onshape complaining about gaps between the outer face of this “wheel” and the "spokes’ (assuming that it’s a wheel):
Again, with appropriate clean up, it should be possible to generate a flow region without issues.
Cheers
