It's not possible to edit STL geometry , then how we can give Boundary conditions For the Complex STL geometry.

Hello,
I would suggest you to either wrap it or convert it to a solid and then apply BC. Again, this depends on the number of facets you have in the model and how intricate your model is.

[Sliceee123]

Model is complex , Is there any better way to do so ..?

How many surfaces do you need? Is the stl one big file or is it made up of multiple bits?

[Sliceee123]

It is one STL file , but the structure is complex .

[Rob]

Are the surfaces you want to split flat? Ie can you use a seed & angle on the surface facets?

[Sliceee123]

Actually I want to do nasal airflow simulation , no surfaces are not flat

[Rob]

In which case can you do some of the separation in the segmentation tool?

[Sliceee123]

Segmentation tool in Ansys?

Fluent Meshing allows surfaces to be split from a seed. I'd get a mesh first though. Otherwise the software that's used to convert from DICOM to stl usually has some very good capping tools.
