Engineering Simulation & Optimization

FEA, DEM-SPH, rotor dynamics and CFD services for design validation, failure investigation and equipment optimization.
ValBrid helps equipment manufacturers and product development teams assess component performance, investigate failures and improve material flow. Our simulation services combine finite element analysis, particle and fluid modeling, and rotor-dynamic assessment to support practical engineering decisions.

Working alongside your engineers, we define each study around the operating conditions, available data and design questions that matter to your equipment.

DEM & SPH Simulation for Bulk Materials and Slurry Flow
Discrete element method (DEM) simulation models particle movement, particle interactions and contact with equipment surfaces. It helps engineers understand granular flow, material accumulation, impact loading and potential blockage zones.

Smoothed Particle Hydrodynamics (SPH) is a mesh-free, particle-based method for simulating fluid motion. Our specialist DEM-SPH capability brings particle and fluid modeling together to investigate solids–slurry interactions, particularly in milling and wet material handling applications.

We assess how equipment geometry, particle characteristics, contact properties, feed conditions and operating motion influence flow and discharge behavior. Comparing design variations helps identify changes for further development, while preliminary wear indicators support assessment of relative exposure.

We have successfully delivered DEM studies that informed iron-ore transfer-chute geometry and liner-zoning recommendations. Our coupled DEM-SPH experience includes mill-discharge modeling, examining the movement and interaction of grinding media, ore and slurry.

Material assumptions, calibration requirements and model limitations are identified so that findings can be interpreted against actual operating conditions.

Finite Element Analysis (FEA) & Multiphysics Simulation
ValBrid provides FEA services for mechanical design validation, fatigue assessment and failure investigation. We evaluate how components and assemblies respond to loads, constraints and temperature, with capabilities covering:

• Structural stress, deformation and local stress concentrations.

• Nonlinear contact and material plasticity.

• Fatigue and service-life assessment under defined duty cycles.

• Thermal and thermomechanical behavior.

• Failure investigation and comparison of design alternatives.
   

We compare agreed design alternatives, identify critical regions and explain the limitations of the results. Findings support targeted design refinement, failure assessment and value engineering against agreed performance objectives.

Rotor Dynamics Analysis Using MADYN 2000
We use MADYN 2000 to assess the dynamic behavior of rotor-bearing systems, including natural frequencies, critical speeds, damping and unbalance response.

Our work includes successful rotor-dynamic model recreation, with key results closely matching a supplied reference model. These studies help engineering teams understand vibration characteristics and assess the influence of shaft, bearing and support assumptions on rotating machinery.

Computational Fluid Dynamics (CFD)
CFD simulation assesses fluid flow and heat transfer to support equipment evaluation and design improvement. We examine flow distribution, pressure behavior and thermal performance around defined operating conditions.
Where appropriate, CFD complements structural and particle analysis. Results can be transferred between methods to assess interactions-for example, applying temperature fields or fluid-induced loads to an FEA model.
We present findings through clear visualizations and technical reports explaining critical results, assumptions and recommended actions. Simulation insights also support our mechanical product design and reverse engineering services.
