Multiphysics Simulation

In traditional engineering, each physical phenomenon is often analyzed independently. However, real-world problems rarely occur in isolation. Multiphysics simulation bridges this gap by enabling the simultaneous simulation of multiple interacting physics within a single model. This allows technology leaders to capture the true essence of complex engineering challenges and achieve more accurate and reliable results.Our CFD, FEA & DEM engineers form strong synergy to develop this cutting-edge approach of Modeling & Simulation. Highlighting the potential with two technologies of CFD-FEA and DEM-FEA coupling. Combining CFD & FEA complex interplay between fluids and structures can be simulated to get valuable insights in problems like fluid-structure interaction (FSI)While coupling of DEM-CFD models the behavior of granular materials interacting with structures. Gain a deeper understanding of stress distribution, particle flow, and potential equipment wear.

CFD–FEA coupling enables a deeper understanding of fluid–structure interaction by integrating Computational Fluid Dynamics (CFD) with Finite Element Analysis (FEA). This combined approach allows engineers to simulate how fluids influence structural performance under real-world conditions, such as pressure loads, thermal stresses, and vibration effects. By capturing both flow dynamics and structural response in a unified framework, CFD–FEA coupling provides highly accurate insights for improving design reliability, reducing failure risks, and optimizing performance across industries like aerospace, automotive, energy, and process engineering.

DEM-FEA Coupling

Tridiagonal specializes in the coupled simulation of Discrete Element Method (DEM) and Finite Element Analysis (FEA), offering detailed insights into the interaction between particulate materials and structural components. By integrating DEM with FEA, we accurately model the behavior of granular materials and their impact on structural integrity, essential for applications in the oil and gas industry. Our simulations provide precise predictions of stress distribution, deformation, and wear within equipment subjected to particle interactions. This coupled approach is vital for optimizing the design and durability of critical components such as pipelines, separators, and drilling equipment. With our expertise in DEM-FEA coupling, we help clients enhance operational efficiency, safety, and longevity of their assets.

CFD-DEM Coupling

CFD–DEM coupling integrates Computational Fluid Dynamics (CFD) with Discrete Element Method (DEM) to accurately simulate fluid–particle interactions in complex multiphase systems. While CFD captures the behavior of the fluid phase, DEM resolves particle motion, collisions, and contact forces, enabling a detailed understanding of granular flow within fluid environments. This powerful approach is widely applied in industries such as pharmaceuticals, mining, chemicals, and energy to optimize processes like fluidized beds, pneumatic conveying, slurry transport, and mixing operations, ensuring better design efficiency, process reliability, and scale-up accuracy.
