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.

This geometry regards the flow over two pipelines along the ocean floor. In order to prevent vortex induced vibrations, helical strakes are placed along the pipelines. Modular mesh generation can be used to replace the pipeline geometry with a straked one without regenerating the entire grid.
