-Since the evolution of the density is not directly tracked in Metafor, in order to take into account the density variation for the computation of the center of gravity and for the mass, the mass matrix is directly employed.
+At each archiving step the extractor fills a four columns text file, where columns 1-3 contain x, y, and z coordinates of the center of gravity respectively, and column 4 contains the value of the mass.

-To compute the center of gravity and the mass of an interaction a density different from zero is needed. Pay attention, when you define your material properties, to explicitly define a $MASS_DENSITY$ different from zero, otherwise a $FATAL_ERROR$ is raised.

 ===== 2. Tests =====
-===== 3. Minor modifications =====
+For the moment, a gravity center and mass extractor has been added in ''apps/imp/bounce.py'' and for all the test cases contained in ''apps/monosMaterials2'' and ''mtThixo/tests/monoMaterials2'' via ''apps/toolbox/materialTesting.py''. A density different from zero has been defined when needed.
