Multiphysics Simulation
Advanced Multiphysics Simulations FEM & CFD for Critical Systems and Equipment in aerospace, nuclear, railway and renewables.
One of the strongest values that OBUU TECH brings to the market is its full capability in Multiphysics numerical simulations to ensure the optimal performance of systems under extreme conditions.
By integrating multiple physical fields, such as structural mechanics, thermal analysis, fluid dynamics, and vibration behavior, we create detailed models that predict how systems will behave in real-world scenarios. This approach is essential for validating the design and functionality of complex systems and equipment used in aerospace, defence, nuclear, and space missions, providing:
Predictive Performance
Identify potential issues before physical testing, reducing risks and costs.
Optimized Design
Improve efficiency and performance by fine-tuning materials, geometries, and components.
Reliability
Ensure the safety and reliability of systems under extreme conditions, meeting or exceeding industry standards.
Qualifications
Structural and environmental qualification by analysis, like transport, thermal behavior, safety and operational loads
Our multiphysics simulation capabilities are powered by industry-leading software such as ANSYS Mechanical and Siemens SIMCENTER3D and our ability to use other platforms if required, enabling us to perform high-precision analysis for a wide range of applications. Whether designing flight equipment for military aircraft, ground equipment for space missions, or critical components for nuclear reactors, our simulations ensure that every system is rigorously tested and optimized for performance, safety, and reliability.
This technique provides a comprehensive analysis of the equipment or system's structural integrity, evaluating its ability to withstand the operational loads, temperatures, and environmental conditions it will encounter. And all of that we document it in a report with steps, results and methodologies used to ensure that each component and assembly meets or exceeds the required safety and durability standards.
The structural analysis follow a phased approach, starting with preliminary calculations during the initial design phase and advancing through intermediate and final analyses. Each phase aims to validate the system's structural compliance with the specified requirements, focusing on key factors such as mass distribution, material selection, modal failure, vibrations and thermal performance.
