We present results of a virtual experiment, carried out by means of a McStas simulation of the powder diffractometer DMC at PSI, using the new powder sample component PowderN. This powder component takes tabulated crystallographic input to define realistic powder lines. The simulated output data from the virtual experiment on the compound Na2Ca3Al2F14 are compared to real measurement data from the DMC instrument. The agreement is very good with respect to peak positions, widths, background intensity and relative peak intensities. This work represents an important step towards reliable virtual experiments and also act as a validation of the PowderN sample component in McStas.
