Gap Closure in Surface Wrapper: Drone Main Body
When using the surface wrapper for geometries that have feature-level holes or gaps, you can find that the core wrapper is unable to cover the whole surface with a closed wrap. To assist, Simcenter STAR-CCM+ provides a gap closure option that detects and fills these larger voids in the surface.

Gap Closure in Surface Wrapper: Drone Main Body

When using the surface wrapper for geometries that have feature-level holes or gaps, you can find that the core wrapper is unable to cover the whole surface with a closed wrap. To assist, Simcenter STAR-CCM+ provides a gap closure option that detects and fills these larger voids in the surface.

This tutorial demonstrates how to extract an external surface from a drone main body (excluding the propellers) using the Surface Wrapper feature with the gap closure option activated. By default, the Use Enhanced Size-based method is activated to control the behaviour of gap closure. The drone main body is composed of two shell parts with grille holes and a camera, as shown in the following images.
