  In this work we introduce the Object Kinetic Monte Carlo (OKMC) simulator
MMonCa and simulate the defect evolution in three different materials. We start
by explaining the theory of OKMC and showing some details of how such theory is
implemented by creating generic structures and algorithms in the objects that
we want to simulate. Then we successfully reproduce simulated results for
defect evolution in iron, silicon and tungsten using our simulator and compare
with available experimental data and similar simulations. The comparisons
validate MMonCa showing that it is powerful and flexible enough to be
customized and used to study the damage evolution of defects in a wide range of
solid materials.
