Abaqus + α Solution "Fluid-Structure Interaction Analysis"

I would like to introduce information about how CAE and CFD are beneficial to society, including interesting application examples, primarily through articles in the information magazine "ADVANTAGE." By using ANSYS CFX, you can obtain information about discharge heads, power consumption, and efficiency, as well as check the flow field within pumps. Today, I will introduce the efforts of CP Pumpen, a leading supplier of high-quality centrifugal pumps, in utilizing simulation for product improvement. To secure a competitive advantage in an increasingly competitive market, they implemented CAE to improve their products. ↓ To improve the traditional prototype-based methods, they introduced ANSYS CFX and ANSYS BladeModeler. ↓ Through repeated pre-validation, they were able to improve hydraulic characteristics and highlight issues with conventional designs. ↓ This led to significant effects, such as a threefold increase in development efficiency (↑) and up to a 50% improvement in pump efficiency (↑), successfully recovering the initial investment within a year. *For more details, please refer to the link below or feel free to contact us.

Today, I would like to change perspectives a bit and introduce the "Fiber Module," an optional feature of ANSYS Fluent. This module allows for the modeling of melt spinning and dry spinning processes in fiber production. It can simulate various physical phenomena such as the solidification of molten liquid and volatilization by coupling the standard CFD mesh of Fluent with an independent one-dimensional mesh (grid) for the fibers. There are three methods for spinning: melt spinning, dry spinning, and wet spinning. Currently, ANSYS Fluent and the Fiber Module can simulate melt spinning and dry spinning. By considering the coupling of surrounding fluid calculations and fiber calculations, it is possible to obtain flow fields and temperature fields of the surrounding fluid associated with changes in fiber flow, as well as local information about the fibers corresponding to changes in the surrounding fluid. All necessary settings for the simulation can, of course, be done through the GUI. A high level of functionality is a characteristic of the ANSYS Fluent Fiber Module. *For more details, please refer to the link below or feel free to contact us.

This time, we would like to introduce an interview article with Sun Medical Technology Research Institute Co., Ltd. They have developed an implantable assistive artificial heart system called "EVAHEART" over approximately 20 years. ↓ While previous assistive artificial hearts were external devices, this implantable version allows for discharge from the hospital and reintegration into society. It is an extremely specialized medical device that, despite being a life-supporting device classified as a high-level controlled medical device, can also be used at home. ↓ The development has benefited from ANSYS products. ↓ Until recently, simulations were outsourced to external research institutions, but in developing the new system, they have started conducting fluid, electromagnetic, and structural simulations in-house to efficiently advance the design of motors and pumps. ↓ Ultimately, biological verification is essential, but by optimizing each component in advance using simulations, they aim to minimize biological evaluations and pursue efficient development. ↓ They want to use simulations as a tool to analyze results and understand phenomena by formulating hypotheses and executing simulations. *For more details, please refer to the link below or feel free to contact us.

I would like to introduce information about how CAE and CFD are beneficial to society, as well as interesting application examples, primarily through articles from the information magazine "ADVANTAGE." Here is an interview article featuring Toyota Motor Corporation. Initially, the company had not made much progress in utilizing CFD due to the complexity of phenomena in the drive system. However, starting in the early 2000s, they began benchmarking for cooling simulations and conducted various verifications over several years. ↓ As a result, they decided on Fluent, which has high accuracy and can reproduce complex phenomena, from among many CFD codes. ↓ Previously, evaluations were conducted through prototypes and in-vehicle experiments, which resulted in significant losses if issues arose. ↓ Now, thermal evaluations can be conducted before the prototype vehicle is created, significantly shortening the development cycle and reducing the number of prototypes. Furthermore, simulation results can visualize which parts are effective for cooling, making it much easier to implement countermeasures. ↓ Until now, CAE has often been focused on cost reduction through the reduction of prototypes, but it is now being used for the purpose of "creating better cars." *For more details, please refer to the link below or feel free to contact us.
