Computational mechanics software is especially called for in the national defense area, such as manned space flight, fighter planes and smaller nuclear weapons. In order for a nation to self-develop high-tech in defense, carrying vehicles, power, energy, mechanics, electrical, electronic, and equipment etc., it must have all kinds of production capacity of major industrial equipment with independent intellectual property rights, as well as related software and talents in computational mechanics and other scientific fields. From this perspective, it can even be said that whoever holds the talents and software in computational mechanics will have more advantage in the global competition.
