Hallo!
I have the model of a UAV as an .obj file.
When i import it to the Design Modeler i get a yellow tic at the Import1, as shown in the image.
It doesnt mean that it is a failure but when i try to create the fluid domain it always fails so i have come to believe its the import that causes the problem.
Does anyone have an idea how to make the import better with a green tic?
Thanks a lot!

Please check geometry in SpaceClaim. 
Select geometry in structure tree --> Use right click --> Select Check Geometry. (Or Tools - Fault Detection in DM)
The geometry should be error free to proceed. 
If geometry has any errors, please modify/recreate geometry at those places. 

While creating fluid domain please make sure that you do have tangential contact between different bodies. Make sure that bodies intersect with each other correctly. 

Please go through help manual for more details

Hallo!
I made a simpler 3D model of the UAV.
I checked the geometry in SpaceClaim and it said: No geometry problems found.
So i import it on DesignModeler and now the tic is green, as shown in the image.
But the problem still exists. I try to make an enclosure and it gets me this message, as shown in the 2nd image.
What should i do in DM to fix it?
Thanks a lot!

Is the issue maybe caused by the thing that is shwon in the image?
Maybe the fact that it is named 6\Facets implies something wrong about the geometry and that is the reason i cant do any boolean or enclosure around it?

Please check other thread. Facets is like STL. You need to create good geometry out of that. 

You can convert faceted data to solid in SpaceClaim. There are different ways to convert stl to solid.

The first one is using Right Click on the body in the structure tree and select Convert to solid option. This option is useful for planner surfaces and simple bodies. If your body has some fillets or curved surfaces, this option should not be used.

 

The other option is using Skin tool. You can find more information about Skin tool in help manual at following link.

In SpaceClaim different commands can be used to create solids from faceted data. Various options are shown in following video.
