The purpose of this paper is to analyze, develop, design, implement, and evaluate the engineering simulation model in metallurgy subject [Rockwell hardness test simulation (RHTS)], according to analyze, design, develop, implement, and evaluate (ADDIE) model and the Mechanical Engineering students of Babylon Institute in Iraq are chosen for case study. This paper presents the various steps involved in the simulation procedures. The detail simulation development process and its signiicant characteristics are highlighted. The lowchart of the model is rendered, displaying the diferent components used to develop the simulation algorithm using Microsoft Studio 2010 computer programming language. The advantages and limitations of the simulation model are identiied by interviewing experts. The indings resulted from the simulated model reveal that the learners can learn easily and efectively. The developed software package is expected to provide valuable tool for both students and instructors. Furthermore, the same package in the form of a bi-product can also be used as a "research tool" together with the application for engineering education.
