Fluid-Structure Interaction - 3D Turbulent Case Simulation of a Fluid-Structure Interaction case of a turbulent flow around a fixed cylinder with a flexible thin rubber plate and a rear mass (Re=30 470). This is an FSI benchmark realised experimentally and proposed by Kalmbach and Breuer [1]. The fluid mesh is composed of about 40 million tetrahedrons, while the solid mesh is made of 900 27-node hexahedrons. This simulation is performed using a partitioned coupling between an Arbitrary Lagrangian Eulerian (ALE) solver with an LES approach, and a Structural Mechanics Solver (SMS), both included inside the YALES2 library. The coupling is performed via the CWIPI library. The mesh movement is computed using a pseudo-solid method, combined with the dynamic mesh adaptation module based on MMG3D. Structure oscillations amplitude has been here predicted with an error of 2.9%, and frequency with an error of 4.2% compared to experimental data.

We have released a new application report comparing Digital Image Correlation (DIC) and Finite Element Method (FEM) for strain distribution measurement on a curved steel beam. This report, following our previous study three weeks ago, provides insights into the effectiveness of DIC and FEM in capturing strain under bending load, using a comprehensive test setup and analysis tools.   #StrainAnalysis #Engineering #DICvsFEM #XSight

Highly accurate laser welding machine. In 2022, we pursued our idea of creating a modular laser machine with the NSPV team and successfully developed one of the most accurate welding machines. This machine can weld within a workspace of approximately 50 x 40 x 30 centimeters. The welding process is very fast, precise, and suitable for miniature components. You can integrate this machine into your production line to increase efficiency. #mechanical_engineer #laser #laser_welding_machine #fiber_laser #automatic_fiber_laser_welding_machine #3d_design #industrial_design #solidworks #Optics #photonics #optomechanics #cad

💡 Did you know the object-based optical model in Quadoa Optical CAD is vastly more intuitive and efficient than standard simulation methods for tolerancing optical systems? Note the following differences in how tolerancing is set up in a sequential surface listing versus Quadoa: ➡ System Setup and Dependencies ❌ Surface List: numerous coordinate shifts and solves must be added to the nominal design to model isolated perturbations, offset pivot points, or assemblies. In this paradigm, all surfaces are defined relative to the prior surface. ✅ Quadoa: native global or local positioning of each component with built-in pivot point definition. This paradigm also supports assemblies and hierarchical referencing for complex tolerance dependencies. ➡ Double Pass Systems ❌ Surface List: duplicate surfaces, coordinate shifts, and solves are required to ensure double pass surfaces see the same perturbations in each pass. ✅ Quadoa: optical components are defined once, separate from ray sequences, ensuring perturbations are automatically the same in all passes. ➡ Irregularity Modeling ❌ Surface List: often requires adding surfaces or changing surface types that further complicates the nominal optical design. ✅ Quadoa: surface stack definition whereby irregularity is added to any nominal surface as a built-in form property. Tolerancing in Quadoa often requires little additional setup or nominal design complication. Once tolerance parameters and ranges are defined, sensitivity and Monte Carlo analyses can be run quickly.

Excited to announce that next week I’ll be presenting at #LaserMatters hosted by MTC - Manufacturing Technology Centre! Join me for my talk, "Predicting and Improving Hairpin Weld Quality with a Process Simulation," where I’ll dive into how advanced simulations can unlock new levels of precision and efficiency in weld quality. Using FLOW-3D WELD, our powerful #CFD software, we’re transforming the way engineers and manufacturers approach welding challenges. By simulating complex thermal and fluid behaviors, FLOW-3D WELD enables users to predict outcomes and improve weld quality via much better understanding of the influence of process parameters. It’s an innovative way to reduce trial and error, save on materials, and ensure high-quality results every time. If you're attending Laser Matters, I’d love to connect and discuss how CFD can support your welding processes. Let’s push the boundaries of what’s possible with laser welding! #LaserMatters #FLOW3D #WeldingInnovation #ProcessSimulation #CFD #LaserWelding #WeldingQuality #HairpinWelding #EngineeringSimulation

Laser cladding is a technique that employs laser technology to melt the surface of the substrate and the addition material, which can be in the form of wire, powder or strip. The process is similar to arc welding, but with the added precision and control of laser technology. This method is used in a variety of industries, including aerospace, automotive, and medical, to improve the surface properties of components. #engineering #technology #technologies #arcwelding #welding #laser #automotive #wire #aerospace #lasertechnology #LaserCladding #WeldingTechnology #PrecisionEngineering

Roughness measurements of metal surfaces Roughness measurements of metallic surfaces are a dominant task in surface measurement technology for many companies and some tasks require the measurement of larger areas with sufficient resolution.
