As a mesh could be built on a CAD definition, a remesh operation could be build directly on a STL file !
This new step allows to reduce strongly the time-to-market as the reverse-engineering step (CAD issue) is no more used : remesh step is directly process on 3D data coming from a digitizing service (CT or optical or on your own !).
Few pre remesh step could be useful as sharp edges reconstruction or holes filling before to apply !
As a high-end issue, remesh service offer a qualitative and quantitative managed mesh usable in the main simulation actual codes (Fluent, Nastran, Abaqus …).
Remesh your data will allow you to be the first on time !
