The NEWT suite of software tools:
solution-adaptive flow solutions

CFD Laboratory, Cambridge University Engineering Department, Cambridge UK

CAD IMPORT (3DGEO)

Imports CAD data containing parametric edges and faces information. Handles native CAD/IGES/STEP geometry and provides an editing and repair system.

CAD REPAIR (3DGEO)

Removes duplicate edges and faces and unused nodes and edges in the data file. Creates automatic topology by automatically identifying all the edges around the faces.

Changing the design of the cooling passage using 3D Geo Editor. The control points on the cooling passage may be edited through the pop-up dialog or dragging the points using left mouse button.

SURFACE MESHER (SRFMSH)

Generates surface triangles on any arbitrary 3D geometry using a Delaunay triangulation algorithm. Features automatic refinement for curvature, proximity etc. The following parameters are very easily controlled - size of the triangles, viscous layers, curvature and 2D to 3D extrusion.

TETRAHEDRAL MESHER (VOLMSH)

Produces a 3D Delaunay tetrahedralisation of the domain. This process also includes optimisation of the quality of the cells. Full 3D Delaunay volume mesher, highly stretched viscous tets near walls together with options for modular meshing.

FLOW SOLVER (NEWT & HYDRA)

The mesh, its connectivity and an initial guess are written out for NEWT solver system or filtered through JM52 to the Rolls Royce HYDRA system.
