MULTIFOAM is a simulation tool developed within the framework of computational micromechanics by IMDEA Materials to predict the mechanical behavior of low to medium density foams with open and closed-cell microstructure. The representative volume element of the microstructure is built from a number of parameters (density, cell size distribution, anisotropy and type, struts and walls mass fraction, mechanical properties of bulk material, etc.). The mechanical properties of foam under different loading conditions (including compression until full densification) are then computed by means of the finite element analysis (Abaqus/explicit) of the representative volume element.

MULTIFOAM is a ready-to-use software package developed using Python which includes a Graphical User Interface. The finite element based modelling strategy of the MULTIFOAM has been extensively validated in the case of polyurethane foams. The tool is fully automatized and could be used for design optimization.
