Independent COMSOL consultant for Complex Engineering Problems

 

 

Physixfactor is an independent COMSOL consultant 20+ years of experience in engineering simulation and finite element analysis. We help companies solve complex engineering problems using COMSOL Multiphysics, from individual simulation studies to long-term COMSOL consultancy.

Our experience covers heat transfer, CFD, structural mechanics, electromagnetics, plasma and custom PDE modelling. We work directly with engineers and R&D teams when specialist COMSOL expertise is required, whether you need help with an existing model, a new simulation, or a complete multiphysics study.

Why work with an independent COMSOL consultant?

 

Complex simulations often require more than knowledge of the COMSOL software itself. The physics, mathematical formulation, numerical methods and modelling assumptions determine whether a simulation produces a useful engineering result.

As an independent COMSOL consultant, we can support your project with both the underlying engineering physics and the COMSOL implementation. This includes developing models from scratch, improving existing simulations, investigating convergence problems and implementing custom PDE formulations when the standard COMSOL interfaces are not sufficient.

Complex Geometry and Submodeling

Large industrial systems often contain critical regions that require significantly higher accuracy than the overall model.

Physixfactor applies submodeling techniques to efficiently capture local stresses, temperatures, deformations and field concentrations without excessive computational cost.

Typical applications include:

  • Welded and bolted connections
  • Offshore structural details and Pressure vessel components
  • Electrical contacts and Thermal hot spots
  • Fatigue-sensitive regions in rotationg machinery

Offshore submodeling example:
Submodelling of an offshore bracket was completely outsourced to Physixfactor. First the geometry and mesh was modefied in order to make a robust model with adequate convergence.  We applied the submodelling techique and identified a critical stress concentration that was missed in the global model. Design was modified before production, preventing a potential field failure. 

Resonance-related failures are among the most costly and preventable problems in mechanical engineering. Understanding dynamic behavior early — before a prototype is built — saves weeks of testing and redesign.

Physixfactor performs modal and vibration analyses to identify natural frequencies, mode shapes and structural response to dynamic loading. Applications include machinery, offshore equipment, support structures, piping systems and mechanical assemblies.

What modal analysis reveals:

  • Natural frequencies and Mode shapes
  • Resonance risks under operational loading
  • Dynamic response to seismic or impact loading
  • Rotating machinery dynamics

EXAMPLE RESULT:

Resonance identified in a pump assembly at 47 Hz, coinciding with operational speed. Geometry adjusted in simulation — problem solved before manufacturing.

Custom Physics and Advanced Equation-based Modeling

Not every engineering problem fits within standard simulation interfaces. Some applications require implementation of proprietary material behavior, custom transport equations or specialized governing equations that no commercial module provides out of the box.

Physixfactor develops custom mathematical models using COMSOL’s advanced equation-based capabilities. This extends simulation possibilities well beyond standard software modules and is particularly valuable for R&D organizations developing novel materials, processes or devices.

Examples include:

  • Custom transport equations
  • Specialized material behavior
  • User-defined source terms
  • Multi-scale models
  • Process-specific formulations
  • Research and development applications

Model Verification and Quality Assurance

A simulation result is only useful if you can trust it. Common pracrice within the workflow of Physixfactor is a mesh test with a solution that converges in closer steps to the true mathematical solution. One has to understand that Finite Element Methods always are an approximation to the ideal mathematical solution. Once you understand this mechanism you can produce results which give you confidence in the next steps to take in your project.

Every project which is outsourced, includes systematic quality checks as standard practice, not as an optional add-on.

Verification procedures:

  • Mesh independence studies
  • Convergence testing and Solver sensitivity analysis
  • Boundary condition verification
  • Solver convergence checks
  • Validation against analytical solutions where applicable
  • Engineering plausibility reviews

Physixfactor places strong emphasis on model credibility and traceability. Simulation results should not only converge numerically but must also remain physically meaningful. In other words, your next steps in the project will be succesful!
