The CENTAUR Modular Mesh Tool offers the important capability to generate derivative meshes from an original mesh by re-meshing part of the geometry while leaving the rest of the mesh unchanged.

The advantages of the approach are minimization of the mesh changes and localization of the setup, yielding faster and more accurate re-designs.

The angle of the flap is changed while the mesh over the rest of the wing remains unchanged. Only the mesh in the affected flap region is re-generated.

The type of elements on the flap surface is changed from prisms to hexahedra. The mesh changes locally only in the flap region:

The angle of the winglet is changed while the geometry and mesh of the main wing remain unchanged. Modular mesh generation allows only the winglet region to be re-meshed, minimizing mesh variation between the different configurations.

A local region/part of the geometry can be changed with only the corresponding local mesh being re-generated:

The pylon connecting the aircraft engine to the wing is being re-designed. A box region is defined inside which the geometry and mesh changes will occur. The mesh over the rest of the aircraft domain remains the same thus reducing mesh variation which may skew the results.
