Simulate small particles’ movements and interactions with the fluid

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: We will soon consider interactions between the particles too

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: More thermo-electrical phenomena will be covered in response to users’ needs

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.

Prevent overheat of electric devices from heat generated by electricity

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.

More accurate and faster Multi-body Dynamics to analyze movements of mechanical systems

3 major changes enhance the MBD in midas NFX:

  1. Significant accuracy improvement by replacing old penalty method with new recursive calculation method led
  2. Eliminate parasite vibration by liberating load application from dependence on length of the time steps.
  3. Improve calculation speed up to 20 times

Daegeun Lim: We want to couple flexible bodies and rigid bodies for more efficient system analysis

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.

Hyeonsang Jang: Two-way fully coupled FSI is in the plan

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.

Apply automatically temperatures and pressures, calculated from fluid analysis, to structural analysis

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.

Why do users love NFX?

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

Piotr Harnatkiewicz, CEO in KOMES Ltd, Poland

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.
