Structural Analysis (Finite Element Analysis)

Types of analysis (FEA):

  • Linear and non-linear static: Response of structure to critical loads and modeling of contact (allowing analysis of assemblies), non-linear material behavior and large deformations
  • Buckling: Critical compression static load or combination of loads that results in instability
  • Normal modes, frequency response and response spectrum: Response to vibrations and frequency driven excitations.
  • Random response: Response of structure to excitations defined with probabilistic magnitude (spectral density function)
  • Transient, dynamic, vibration and seismic response: Response of structure through time with variations of boundary conditions
  • Impact (implicit and explicit solvers): Response of structure following collision (crash tests and drop tests)
  • Steady state and transient heat transfer: Temperature distribution within a solid body
  • Thermal stress: Stress induced by temperature distribution
  • Fatigue analysis (multi axial and vibration fatigue): Predict the life of a structure subjected to cyclic loading or vibrations

Types of materials:

  • Isotropic for standard metallic or non-metallic materials
  • Orthotropic and anisotropic for material properties showing direction dependency like composite or wood
  • Hyperelastic for rubbers and elastomeric
  • Non-linear material behavior for materials sustaining permanent deformations (e.g. plasticity) or showing complex behavior (e.g. non linear elasticity)
  • Material behavior driven by experimental data (linear and non linear) allowing highly accurate representation of material used by customer

Computational Fluid Dynamics (CFD)

  • Steady state and transient CFD simulations of internal/external liquid and gas flows
  • Analysis, design and optimization of immersed or surrounding components
  • Optimal turbulence modeling approaches: RANS, URANS, RSM, LES, DES
  • Incompressible, transonic and compressible flows
  • Rotating equipment and moving bodies
  • Multiple reference frames, rotating and sliding interfaces, deformable meshes
  • Fluid-structure interaction
  • Heat transfer and thermal modeling
  • Multiphase and free surface flows
  • Flow mixing
