OUR SUB-SERVICES
Simulation Sub-Services
1- Fluid Analysis (CFD)
Our CFD (Computational Fluid Dynamics) simulations are conducted using Simulia (Dassault Systèmes) and OpenFOAM, allowing us to analyze airflow, thermal management, and hydrodynamic performance with high precision.
• RANS solver for steady-state and long transient simulations physics covered:
o Incompressible and compressible flow
o Conjugate heat transfer with radiation
o Multi-species & free surface flows
o Newtonian & non-Newtonian flows
o Fans, porous media
o Electronics cooling components
o Whole body thermal comfort
o Multiple reference frames (MRF)
• Laminar and Turbulent
o Turbulence models:
• One-equation model: Spalart - Allmaras
• Two-equation model: Realizable k-epsilon, SST k-omega
o Near-wall modeling is based on a hybrid wall-function approach that is fully scalable and parallelized.
2- Structural Analysis (FEA)
We perform FEA (Finite Element Analysis) using the 3DEXPERIENCE Platform (Abaqus solver) to evaluate stress, vibration, and durability, ensuring robust and reliable designs.
• Steps
o (Static, Quasi-Static, Implicit Dynamics, Static Perturbation, Buckle, Frequency, Harmonic Response, Modal Dynamic, steady state heat transfer, Transient heat Transfer, Automatic Step Stabilization, Explicit Dynamic)
• Interactions
o (Contact Control, Contact Detection, Contact Initialization, Contact Interference, Contact Properties, General Contact, Surface Based Contact)
• BCs
o (Clamps, Rotation, Velocity, Translation, Fixed Displacement, Accelerations, Hinges)
• Loads
o (Gravity, Forces, Heat Fluxes, Pressures, Torques, Volumetric Heat Sources, Bearing, bolt force & torque)
1- Plastic Injection Molding
Through Moldflow simulation, we optimize plastic part filling, minimize defects, and enhance manufacturability for injection-molded components.
o Complete Fill Prediction: Determines whether the part will fill completely under given processing conditions.
o Weld Line Identification: Locates weld lines and assesses their impact on part strength and aesthetics.
o Air Trap Detection: Identifies potential air traps that could lead to voids or burn marks.
o Optimal Gate Location Analysis: Recommends the best gate positions to ensure balanced filling and minimize defects.
o Multi-Cavity Balance Verification: Checks if all cavities fill uniformly to maintain consistent part quality.
o Injection Pressure Estimation: Calculates the required injection pressure to achieve complete mold filling.
o Material Change Impact Assessment: Evaluates how different materials affect flow behavior, cooling, and final part properties.
• Powerful Virtual Workstations (VDI) High-End Virtual Machines starting at:
o 64 CPU Cores
o 256 GB RAM
o NVIDIA A40 GPUs (for accelerated computing & visualization)
o No hardware limitations, scale up for large, complex simulations.
• Advanced Licensing with Dassault Systèmes Token-based licensing enables:
o Parallel simulation tasks (run multiple jobs simultaneously)
o Optimized core allocation (automatically selects the best number of cores based on mesh size)
o Faster solver performance (reduced simulation time with efficient resource usage)
