Many industrial equipment and processes involve fluid and particles in one system, where engineers want to understand the interaction between particles and the fluid. Typical applications include filtration, solid-liquid mixing, spray coating, etc.
With the newly implemented particle analysis, you can analyze the movements of particles inside the fluid and their interactions with the fluid.
Noh-Hoon Lee, specialist and lead developer of particle analysis solver, explained his future plan in the interview. The next step is to implement “Discrete Element Method” to consider interactions between the particles.
He also wants to couple it with other analyses, such as chemical reactions and species advections. So it will be possible to consider particles as elementary chemical elements and calculate the reactions between them.
Seokgeun Yi, lead solver developer for Joule heating function, explained the project which took the team 6 months. The team is currently working on implementing other thermos-electrical phenomena such as Seebeck Effect, the Peltier Effect and the Thomson Effect. Users’ needs and feedbacks are the motivations of the team’s hard work.
Most failures of electric products occur because of heat and stress generated from electricity. When electric current passes through a semi-conductor, heat energy is generated and temperatures at certain spots become too high. Without being discovered and dealt with at the design stage, this problem will lead to costly redesign or even product failure.
Joule heating calculates heat energy generated during the passage of electric current through a semi-conductor. It helps designers to spot the overheated areas and make proper improvements to their designs.
3 major changes enhance the MBD in midas NFX:
MBD opens the possibility to analyze dynamic behavior of complex mechanical systems. Thanks to it engineers can simulate cars, planes and boats in detail. But the development to MBD will not stop at the the rigid level. Daegeun Lim, lead developer of MBD solver, revealed the future plan of coupling flexible bodies and rigid bodies in one system.
Shortly after the new release, Hyeonsang Jang, lead developer of FSI solver, started to prepare for the next step of FSI. With fully coupled FSI, deformation of the structure can be updated and sent back to fluid analysis. That will simulate the real interaction between fluid and structures.
In many cases, engineers need to use fluid analysis and structural analysis together — calculate the thermal stress of an electronic board; examine the stress on a plane’s wing; investigate influence of wind or fire on architectures.
One way FSI (Fluid Structure Interaction) is developed to facilitate these situations. Analysis results of fluid analysis (temperatures, pressures) can be automatically applied to structural analysis as analysis conditions.
You can simulate nonlinear elastic material in NFX 2015. See how to do it in this example.
Taking into account the effective thermal conductivity of a multi-layered PCB used to be a challenging task. See how NFX 2015 makes it easier for you
CTM is a siplified behavioral model which accurately predict temperatures at critical points (i.e.junction) in a electronic systm. It significally reduce the computing time
Many structures repeast around an axis (i.e. fans, turbines). For these structures, NFX 2015 can pattern geometries and loads cyclically, so you only need to model one small section to evaluate the behavior of the whole structure
In complex fluid flow problems, not every geometry can be well represented using a single, contiguous mesh. NFX 2015 introduces overset mesh function. Try how it works in this example
This function helps to analyze flow, heat, and mass transport in complex pipe networks easily with great saving of computational time. Try how to create 1D CFD element and how to connect it with 3D domain
Inertia relief enables the analysis of unsupported systems such as automotives in motion, or satellites in space. It releases the inertia effect and the relative displacements are independent of constraint conditions.
This tool helps you easily select geometries, which are difficult of access, inside the model.
Continuous Improvement, relentless development. Because we understand the tool that engineers need, and we care
The interface seem modern and intuitive, it still has the range of powerful tools that I use every day. Furthermore, these tools are presented in a single interface, where I can seamlessly change from geometry, to mesh, to boundary conditions, to results, in seconds...
NFX was the solution that HGS had been looking for. The software interface was easier to learn and use, enabling us to integrate NFX into the design pipeline more quickly. The solving speed is particularly impressive, which allows HGS to make more efficient use of computing resources.
Superb support
Our Office is using many FEA packages and personally I think that support provided by midas NFX team was the best that we ever received, despite the distance between Poland and South Korea. Feedback time is in most cases shorter than 24h and very professional
Time and resource saving
Midas NFX played important role by allowing us to analyze different geometry variations before deciding on a final product. This way we saved a lot of time, man power and money and we end up with a product that satisfied the safety requirements.
Friendly and Robust
The robustness and user interface is miles ahead of the other CFD package I had been using
