2C. Particle type modifiers

--(***) All the commands listed here are not considered if system exporation from a previous simulation is done

Once we have our system defined with the desired shape and topography, we can change locally the constituent atoms or particles. Very similar commands to the shown ones in the previous section do the job. A region of the system sees its type changed into a final atom type:

The parameters of this last command CHANGE_GENERAL_ELLIPSOID_TYPE indicates the coeficients of the ellipsoid general equation Ax^2+By^2+Cz^2+Dxy+Exz+Fyz+Gx+Hy+Jz+K<1 The parameters of the CHANGE_PLANE_TYPE command indicates the coeficients of the plane general equation
