STL File Processing

droneCFD can manage some simple STL processing tasks. This includes opening STL file, translating and rotating geometries, bounding box evaluation and saving STL files.

The first task is to ensure that the geometry is centred in the simulation domain. To do this, the bounding box is calculated and a translation vector is generated. This translates the centre point of the aircraft geometry to the origin of the simulation domain.

Additionally, geometries can be rotated. At the moment, droneCFD limits geometry rotation to rotation about the y axis. This is accessed using the --aoa command line argument.
