CAE analysis consulting
We use CFD and motor FEA to assess product performance and design conditions quantitatively, from defining the analysis through computation, verification, interpretation and technical reporting.
How we approach
We start with the design decision you need to make, then set the scope, accuracy and verification method. CFD quantifies flow and thermal performance; motor FEA focuses on electromagnetic behaviour.
We use our in-house solvers alongside proven commercial and open-source codes, selected for the purpose. The results come with the modelling choices, assumptions, limitations and any further verification required.
Analysis disciplines
Use either discipline on its own, or carry losses from the electromagnetic model into a thermal-flow analysis.
Computational fluid dynamics
We calculate the flow and thermal performance of products and equipment, from a single operating point to design comparisons and operating-range studies.
Typical outputs: Pressure, velocity and temperature fields, performance coefficients, pressure loss and heat flux
Finite element analysis
We use finite element analysis primarily to assess the electromagnetic behaviour of electric machines against their design requirements.
Typical outputs: Flux density, torque and ripple, losses and time histories
Engagements
Duration, scale and cost follow from the discipline, model complexity and number of conditions. We estimate them with you.
Single study
A single configuration computed at agreed operating conditions.
Design iteration
Multiple design candidates computed on the same basis so they can be compared.
Parametric study
Geometry or operating variables are changed systematically to map performance trends.
Custom
We define the scope with you when the work involves coupled physics or specialised deliverables.
Scope
Each item gets an appropriate model and convergence criterion, with comparison against test or published data and grid or mesh sensitivity where needed.
We calculate pressure and velocity fields around external geometry and through internal passages, then identify where performance is lost.
Flow rate, pressure loss and flow fieldsWe calculate the rotating flow through fans, blowers and pumps and compare performance and efficiency across operating conditions.
Performance curves and efficiencyWe combine fluid flow and solid conduction to assess cooling performance and temperature fields in motors and equipment.
Temperature fields and heat fluxWe calculate fields in the rotor, stator and air gap to assess torque, ripple and the principal losses.
Flux density, torque and lossesWe calculate mean torque and torque ripple across operating conditions and compare electromagnetic performance between designs.
Torque curves and operating behaviourLosses from the electromagnetic model become heat sources in the thermal-flow model. Structural review is scoped separately when required.
