The subject of boundaries is quite complex because their role in modelling is not simply that of a geometric entity but an integral part of the solution and numerics through boundary conditions or inter-boundary ‘connections’. Web18 de mai. de 2024 · ACMI is an extension of AMI for coupled patches which only partially overlap. Where faces overlap, they couple to one another. Faces which do not overlap the opposing patch adopt a suitable boundary condition, e.g. wall. For faces that partially overlap, ACMI determines the overlapping fraction from interpolation weights.
