@Rahul R Tetramesh update based on geometry modification is USELESS for the question of @jss. His 3D mesh is based on STL, not geometry.

yes, my 3D mesh is based on stl. I don't have solid geometry.

Convert stl back to solid geometry, 

Subtract geometry parts

Then convert geometry to stl to finish!

Thank you for your suggestion. But It is not clear to me, how to convert stl to solid geometry? STL file has very irregular and complicated shapes. 

Menu : 'Geometry' => Create => Surface => From EF

When you have closed surfaces, you can create Solid.
