Fluid-Structure Interaction Analysis

Fluid-Structure Interaction Analysis

More realistic CAE with coupled analysis of Abaqus/STAR-CCM+.

Around us, various physical phenomena such as fluids, structures, electromagnetic fields, and acoustics are intricately intertwined to form a "multiphysics" environment. To accurately capture these phenomena in CAE, it is necessary to model them while considering multiphysics. In this context, the functionality and performance of software and hardware continue to improve rapidly, establishing a foundation for coupled analysis that takes multiple physical phenomena into account. Due to demands for cost reduction in product development and shorter development cycles, the need for improved accuracy and practical application of CAE is increasing daily. Therefore, at IDAJ, we provide a comprehensive support for multiphysics CAE by simultaneously proposing Abaqus and the general-purpose thermal fluid analysis program STAR-CCM+. Coupled analysis using Abaqus and STAR-CCM+ enables more realistic and accurate analyses.

[Fluid-Structure Interaction Case] Destruction Behavior of Reinforced Concrete Slabs Due to Underwater Explosion

[Fluid-Structure Interaction Case] Destruction Behavior of Reinforced Concrete Slabs Due to Underwater Explosion

The water confinement effect is more powerful compared to air explosions! This is a case that shows the destruction situation of the RC version is significantly different.

This is a case study that examines the destruction behavior characteristics of reinforced concrete slabs (RC slabs) due to underwater explosions through numerical simulations using coupled structural-fluid analysis. The explosive used is the H51 model (Pentolite 51g), and the pressure calculations for the model utilize the JWL (Jones-Wilkens-Lee) equation of state. For water, the compressibility is taken into account using the GRUNEISEN equation of state. As a result, in the case of underwater explosions, the RC slab experiences shear failure due to the immense pressure from the water's confinement, while in the case of aerial explosions, craters, spall failures, and cracking occur on both the top and bottom surfaces of the RC slab. [Analysis Settings] - The explosive is the H51 model (Pentolite 51g), and the pressure calculations for the model utilize the JWL equation of state. - For water, the compressibility is taken into account using the GRUNEISEN equation of state. *For more details, please refer to the related links or feel free to contact us.*

Coupled analysis with 3D simulation (VPS)

Coupled analysis with 3D simulation (VPS)

Introduction to the current situation regarding updates on coupled analysis with VPS.

I would like to introduce the current situation regarding updates on coupled analysis with VPS (Virtual Performance Solution). In the GUI, we create models for coupled analysis using ESI Group's integrated GUI environment, VE (Visual Environment), specifically Visual-Systems. With the release of VE 13.5, the number of available components has increased. Specifically, in the previous version, the outputs from the VPS model were limited to position, displacement, angle, and angular velocity. However, in the current version, it now supports displacement and load, and the outputs to the VPS model have expanded to include not only load and pressure sensors but also displacement, velocity, and moment. This significantly broadens the range of cases for conducting coupled analysis. *For more details, please feel free to contact us.*

Press molding and mold deformation weakly coupled analysis ASU/ISTR

Press molding and mold deformation weakly coupled analysis ASU/ISTR

This is an introduction to press forming simulation that takes into account mold deflection using "ASU/ISTR" and "ASU/P-form."

In the current press forming simulation, the mold is treated as a rigid body, and deflection is not taken into account. However, during actual press processing, especially when forming high-strength steel plates, a very large load is applied, resulting in mold deflection. This causes changes in the clearance between the upper and lower molds, leading to variations in contact and surface pressure on the workpiece depending on the location. Additionally, the amount of deflection varies based on the structure of the mold. To reproduce the phenomena of actual press processing in press forming simulation, an analysis that considers mold deflection is necessary. We will introduce a case of forming simulation that takes mold deflection into account using the open-source structural analysis software FrontISTR for mold deformation and our solver ASU/P-form for weakly coupled analysis. ASU/ISTR is a general-purpose pre- and post-processing software developed by our company that is compatible with FrontISTR. By utilizing the deflection weakly coupled setting function of ASU/ISTR, we can quickly incorporate the analysis results from ASU/P-form and automatically set the conditions. Furthermore, it allows for easy analysis setup and execution on a Windows PC. FrontISTR excels in parallel computing, and there are no licensing costs even when using a PC with a high number of cores.
