Simulation of RTM processes in thin plate geometries is usually performed in 2D. Thus,only a mesh of the middle plane is needed with the associated degrees of freedomyielding significant savings with respect to a fully 3D modeling. However suchmodeling needs the definition of an equivalent in-plane permeability representing theignored dimension (the plate thickness). The definition of such permeability is not atrivial task because each ply in the thickness direction can be anisotropic, the principalanisotropy direction being different from one ply to the neighboring plies. In this workwe propose a novel fully 3D modeling whose computational cost of the same order as a2D solution. It allows addressing properly the equivalent in-plane permeability issue aswell as other issues induced when averaging over the thickness dimension.
