In this paper, we show how to compute an orthogonal mesh that strictly conforms to a given simplicial complex SC in ^d. This result will be applied to improve the treatment of wells in oil reservoir simulation. The trend for this problem is to use hybrid meshes obtained by inserting radial well meshes in a structured reservoir grid. Our work can be used to generate a transition mesh connecting the reservoir mesh to well meshes and preserving strict conformity.
