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).
