Hi everyone,

I need to compute results of a simulation on specific surfaces of my geometry.

The geometry consists of a small tube with side-holes put inside a bigger conduit.

If you have holes from one pipe to the other it may be easier to just slice the volume at a mid-hole position radially. Surfaces then exist in CAD and can be labelled for easy post processing. nIf imprint is doing something odd check the scale of the stl coming out of Solidworks. Fluent defaults to metres so there's a good chance the surfaces are either tiny (mm) or huge (km). n

Thank you for your answer.nIf I make them in CAD then I think I will have new edges at the side holes and they will have an influence on my mesh.nI checked the scale by importing the stl in SpaceClaim together with the geometry. The scale seems fine but surfaces are shifted. I have tried just on the tube for semplicity.nnnAnd the same happens in fluent: nn

[Rob]

Where's the origin in Solidworks compared to SpaceClaim? I wonder if you've got an offset for some reason. n

[clabr]

Origin seems to be in the same positionnI have noticed that if I import these surfaces in SpaceClaim as iges or parasolid (and not stl) there is no shift but I don't know if I can import these formats in Fluent in order to do the postprocessing.n

[Rob]

And if you export those faces from SpaceClaim as stl? n

It worked!! Thank you!n
