Independent COMSOL consultancy for Complex Engineering Problems
When standard FEM tools fall short – or your simulation results do not converge, don’t match physically reality, or take days to run – Physixfactor steps in.
We build robust, verified multiphysics COMSOL models that support real design decisions, not just pretty plots. Serving industrial manufacturers, offshore engineers, R&D teams and high-tech equipment developers.
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:
Submodeling of an offshore bracket identified a critical stress concentration that was missed in the global model. Design was modified before production, preventing a potential field failure.
Modal Analysis and Dynamic Behaviour
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.
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. Physixfactor places strong emphasis on model credibility — results must not only converge numerically but must also remain physically meaningful.
Every project 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
- Conservation 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.
