First Claim
1. A method for determining the porosity of a flexible porous structure when it is subjected to deformation, comprising performing the following steps by means of processing representative data of said flexible porous structure:
- a) generating a first function (Fs) defining how at least one part of the flexible porous structure, given its coordinates, changes shape when it is subjected to one or more geometric deformations, wherein said change of the shape is determined in two directions, one in a cross-section of the flexible porous structure (Fs1) and the other in a longitudinal direction (Fs2);
b) generating a second function (Fp) defining how a covered surface, and/or a variable associated with same, for at least one part of the flexible porous structure, changes when it is subjected to one or more changes in shape, said second function (Fp) being directly linked with porosity of the flexible porous structure;
c) obtaining, by means of said first function (Fs), reference porosity values of at least one reference region (CU-R) of the flexible porous structure in a reference configuration; and
d) calculating the porosity of at least one deformed region (CU-D) of the flexible porous structure corresponding with said reference region (CU-R) but for a deformed configuration different from said reference configuration, from said obtained reference porosity values of the reference region (CU-R) and from at least said second function (Fp).

Abstract
A method, system and computer program are provided for determining the porosity of a flexible porous structure when it is subjected to deformation. The method performs the following steps by processing representative data of the flexible porous structure: a) generates a first function (Fs) defining how the flexible porous structure changes shape when it is subjected to deformation; b) generates a second function (Fp) defining how a covered surface of the flexible porous structure changes when it is subjected to changes in shape, wherein the second function (Fp) is directly linked with porosity of the flexible porous structure; c) obtains reference porosity values of a reference region (CU-R) of the flexible porous structure in a reference configuration via the first function (Fs); and d) calculates the porosity of at least one deformed region (CU-D) of the flexible porous structure, from said reference porosity values and from the second function (Fp).
