Research and development in defence industry pioneered numerical methods to gain insight, foresight and trouble shoot performance issues before prototyping of conceptual designs. In FlowXplore, the accuracy of our CAE simulations has increased further to the point where the effect of very small incremental changes in a design can be confidently captured with great accuracy and reliability. This has allowed defence industry to gain further benefit from our CAE solutions by focusing on building more efficient, lighter, stronger, safer and more survivable defence systems.
