Generation of a virtual micrograph of a porous material

LEG program (LERMPS Ellipses Generator) has been developed to produce images equivalent to microstructures and well adapted to finite element analyses.
It can be used in two cases:

Case 1 - The material to be modelized exists and micrographs have been analyzed and characterised by a set of ellipses.
To eliminate unrealistic overlapping of these ellipses, LEG is used to redistribute them randomly in the picture, saving the initial matrix % by an adjustment of the picture size.

Case 2: The material to be modelized does not exist yet, but can be described by a set of ellipses equivalent to the pores and particles of additional phases included in a metallic matrix.

Assuming some limits for the areas, shapes and angles of these ellipses, LEG can generate a random set of ellipses and distribute them with a given density to produce the same kind of images as those deduced from real micrographs.
