An Object-Oriented Toolkit for Solving Partial Differential Equations in Complex Geometry

A snapshot of Ogen being used to generate a grid for a submarine.

Ogen: An overlapping grid generator.

1. automatic hole cutting and grid connectivity algorithm.
2. generates grids for arbitrary order of accuracy.
3. generates grids for multi-domain problems (e.g. multi-materials, fluid-structure interactions).
4. can generate grids with large number (billions or more) grid points in parallel.
5. interactive interface for constructing grids.
6. called from Overture programs for moving grid problems.
