midas NFX 2013: Towards a New Generation of Mechanical FEA Solution


Published on

Slides version for NFX 2013 Online Release Seminar. This webinar Introduces and demonstrates enhancements of NFX's new updates: such as Mid-Surface Extraction, Implicit Nonlinear Dynamic Analysis, Transient Nonlinear Heat Stress, Optimization....

NFX is a FEA generalist software committing to make your FEA work efficient and cost effective. Go achieve this goal, NFX carries 3 most distinguishable characteristics:
1) CAE/CFD solution-in-one interface: This makes NFX more multidisciplinary, and seriously saves your effort to switch between platforms.
2) Intuitive workflow and GUI: NFX is designed to carry out complicated tasks in headache-free ways. Consistent feedbacks about “fast learning curve” and “junior engineer friendly” make us confident to claim for the best in this one.
3) High-end analysis capacity with affordable price:  provides total solutions from high-end structural analysis functions such as contact analysis, nonlinear analysis, explicit dynamic analysis and fatigue analysis in addition to high-end fluid analysis functions such as moving mesh, free surface analysis and mass transfer analysis.
