Most recent algorithms for Geometry Processing or Computational Fluid Dynamics (CFD) are using new types of grids made of arbitrary polyhedra, in other words strongly unstructured grids. In case of CFD simulations, these grids can be mapped with scalar or vector fields representing physical properties (for example : density, porosity, permeability). This thesis proposes new tools for visualization and computation on strongly unstructured grids. Visualization of such grids that have variable geometry and topology, poses the problem of how to store data and how algorithms could handle such variability. Doing computations on such grids poses the problem of solving large sparse unstructured linear systems. The ever-growing parallel power of GPU...
