Validate before fabrication
Check load paths, stiffness, critical details and margins before committing to fabrication or a costly modification.
Advanced analysis · FEA
Finite element analysis for complex engineering decisions.
Understand real behaviour before you fabricate, modify or approve — stress, fatigue, buckling, contact and nonlinear behaviour.
The required outcome: a margin, governing mechanism, comparison or reinforcement detail to establish.
The required outcome may be a margin, governing mechanism, concept comparison or reinforcement detail. We begin with equilibrium and analytical calculations, then refine the numerical model only when geometry, contact, nonlinearity or loading requires it.
When to use FEA
When geometry, loads or behaviour exceed a simple check.
FEA is useful when it reduces a real uncertainty: before fabrication, to understand a failure, or to modify equipment with controlled margins.
Understand a failure
Connect cracking, deformation, vibration or wear to loads, contact, local concentrations and system behaviour.
Modify with confidence
Compare concepts, reinforce only where needed, reduce mass or adapt existing equipment without shifting the problem elsewhere.
Evaluate fatigue
Identify critical ranges, sensitive details and the cycles that govern useful life.
Check stability and buckling
Distinguish a strength limit from global or local instability using the appropriate level of nonlinearity.
Represent contact and gaps
Model supports, friction, bolts, pins, interfaces and load transfer when simple assumptions are no longer sufficient.
The useful model, not the largest model
What the model must actually represent.
A colour contour is not a conclusion. Credibility comes from representing the loads, interfaces, materials and mechanisms that govern behaviour.
- Loads, supports and interfaces consistent with the real assembly.
- Mesh refinement where it affects the engineering decision.
- Contact, gaps, friction and plasticity only when their effect matters.
- Independent checks: equilibrium, convergence, sensitivity and order of magnitude.
- Interpretation of singularities and local concentrations rather than blind use of a peak value.
Analysis capabilities
The right level of physics for the decision at hand.
The scope can range from a focused check to a complete nonlinear analysis. Phenomena are added only when they materially affect the response.
Static
Stress, deformation, stiffness, load paths and reactions.
Contact and nonlinear
Gaps, friction, large deformation, plasticity and progressive behaviour.
Fatigue
Stress ranges, welded or machined details, cyclic loading and life.
Buckling
Eigenmodes, imperfections, post-buckling and local or global stability.
Dynamics
Natural modes, harmonic response, shock, vibration and transient loading.
Thermomechanical
Temperature, expansion, gradients and coupled thermal stress.
Local details
Submodelling, welds, attachments, notches and concentration zones.
Comparison and optimization
Design alternatives, mass reduction, targeted reinforcement and robustness.
Method
A transparent analysis chain, from the question to the recommendation.
Each step must be explainable, verifiable and connected to the engineering decision.
Frame the question
Define what must be demonstrated, the useful level of fidelity, load cases and acceptance criteria.
Build the model
Simplify without losing important behaviour, represent interfaces and focus detail where it matters.
Verify the solution
Check equilibrium, convergence, mesh sensitivity and consistency with independent calculations or observations.
Interpret and recommend
Connect results to failure modes, compare options and provide an actionable conclusion.
Deliverables
An answer that design, fabrication or approval can use.
Results are structured to support a decision, not merely to document that a model was run.
Assumptions and scope
A clear record of inputs, load cases, simplifications, materials, interfaces and criteria.
Interpreted results
Contours and plots accompanied by an explanation of critical areas, limitations and sensitivities.
Decision and recommendations
A clear answer on what works, what governs and what must change, with an engineering report when required.
Frequently asked questions
What to know before getting started.
An initial discussion usually confirms the level of analysis, missing inputs and the best path to a useful answer.
What information is needed to start?
Available drawings or models, known loads, supports, materials, the observed issue and the decision to be made. An initial review identifies what is actually missing.
Does the model always need to be highly detailed?
No. The best model represents the governing mechanism with the detail needed for the decision — not necessarily the largest model possible.
Can you analyze existing or damaged equipment?
Yes. Measurements, photos, load history and field observations can be combined with analysis to understand behaviour and assess modifications.
Can the report support approval or independent review?
When required, the method, assumptions, results, checks and conclusion are documented in an engineering report suited to the project context.
Start simply
A critical component, a modification or a failure to understand?
Send the drawings, models, photos and available information. An initial review will quickly frame the useful analysis.
