Abstract:
1. A computation method for simulating behavior of a flow interacting with an object, comprising the steps of: developing a simulated numerical representation in N dimensions, N≧3, composed of a plurality of approximated values at a multitude of points in at least a part of space where a flow interacts with an object, the approximated values being of a physical parameter u of the flow to which is associated a velocity field {right arrow over (a)} which determines a preferential direction by executing a numerical scheme wherein at least one spatial p i) constructing a discrete N-dimensional grid constructed by N families of coordinate lines and using the constructed grid for the part of space, ii) computing, in at least one point P of the grid, called the point of computation, an approximated value of D iii) choosing the computational functions for the approximated value D wherein the stencil S contains at least one point situated outside all the coordinate lines passing through the point of computation P, and the stencil S contains at least a first point and a second point, the first point being defined by N first coordinate lines of the N families of lines, the second point being defined by N second coordinate lines of the N families of lines, and for at least one family N outputting the simulated numerical representation that simulates, for the part of space, the behavior of the flow interacting with the object; and determining the behavior of the flow interacting with the object by using the output simulated numerical representation.
