DARWin-METM builds on the research-grade MEPDG software version with additional key enhancements.The national calibration-validation process was successfully completed for MEPDG. Although this effort was comprehensive, further calibration and validation studies in accordance with local conditions were highly recommended by the MEPDG as a prudent step in implementing a new design procedure that is different from the current procedures
