Geometric aids customers to build high quality CAE and CFD models for Impact, Durability, NVH (Noise Vibration Harshness), Moldflow, Thermal and Fluid flow mesh analysis for reduction in costs and delivery time. Our global expertise in this domain include technologies like ANSA, HM, PATRAN, ICEM, Fluent Pre/Pro, Moldflow and VISCART/CFD-ACE+

Our expertise in FEA includes the following Engineering areas.

Durability Analysis

Estimating the life of a product is a critical stage in various domains like Automobile, Aerospace and General Engineering. We, therefore, provide Durability Analysis to evaluate the overall life of the structure for a given loading condition. Our work in this area includes :



NVH Analysis

Noise, Vibration and Harshness analysis is performed to understand the behavior of structure when subjected to dynamic loading conditions. Our competencies include :



Impact Analysis

Impact analysis is performed to understand energy transmitted and dissipated in structures undergoing large strain and large deformation under the influence of impact loads through :


 

CFD aims at a fundamental understanding of temperature and flow in physical systems to aid engineering design. To ensure this we utilize our expertise in StarCD, VISCART, ANSA, Fluent and CFD-ACE+ to offer the following solutions :

Geometric provides full scale solutions for part design validation for manufacturability and process optimization in sheet metal stamping, casting simulation and injection molding simulation.

Sheet Metal Stamping and Tube Forming Simulation

• Binder wrap & stamping simulation: Predicts sheet thinning, wrinkles, forming limits, process parameters (BHF, Punch, Speed, lubrication etc.,) & draw bead locations
• Multi-stage stamping simulation: Analyzes different stages of forming & trimming by considering the effect of previous stages in the analysis
• Initial blank size & Shape optimization: Optimizing blank size & shape considering the sheet material cost, forming quality and defects
• Spring back analysis: Predicts the final formed shape after trimming
• Hydro forming simulation: Simulation of both tube & sheet hydro forming
   

Casting Simulation

Die casting simulation is used to predict, flow, solidification, porosity, and tooling optimization for gating, overflows and cooling systems.
