how to subtract two tetramesh components from one another in hypermesh? 

 I was having stl files, then I have converted them into 3D tetramesh. Now i want to subtract volume of one part from other.

    Latest version of HyperMesh 2019.0 provides Tetramesh updates for geometry modification. Please refer attached video.

    @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.

    I cannot select solids in boolean opeartion. STL parts are converted into 3D mesh

    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.
