11CAE Software for the analysis of electromagnetic devices

Software synergyPerfect integration into the CAE chainFlux communicates easily with numerous tools: ▪ To co-simulate with Portunus system simulation (also giving access to Pspice) ▪ To co-simulate with Matlab / Simulink for drive and control devices ▪ To import motor templates from SPEED ▪ Co-simulation with other physics disciplines

Flux is the most open electromagnetic simulation tool on the market, therefore Flux naturally fits within your existing toolchain.An easy control for your specific needsWith its command language derived from the well known Java and Python object oriented languages, Flux allows the user to define its own macros and interfaces to simplify its work, from generating geometry through to post-processing solution results.

Presented in different ways ▪ Colour shaded maps and isovalues plots ▪ Vector plots ▪ 2D and 3D curves as a function of varying

parameters on a path, a grid, probe … ▪ Spectral analysis ▪ Cutting planes ▪ Look up tables ▪ Extensive export capabilities (Excel, text,

AMESim…) ▪ AVI animations, png drawings ▪ User defined postprocessing box

Advanced modeling techniques for accurate and fast results: ▪ Non meshed coils ▪ Thin regions represented by surface models

(no need to mesh the thickness) ▪ Skewed geometries

Complex electrical circuits: ▪ Voltage, current sources ▪ Resistors, capacitors, inductances ▪ Diodes, interruptors, thyristors ▪ Squirrel cage

Rigid body motion: ▪ Translation, rotational and pivotal ▪ Free movement

GOT-It optimizationSearch the design space in an efficient wayBoost your Flux capabilities using GOT-It, CEDRAT’s powerful and reliable optimizer, even without being an expert in optimization methods. Well adapted to drive FEM models, GOT-It goes beyond simple parametric studies, allowing to obtain significant gains in your designs.

Multiphysics interoperabilityCEDRAT has developed an API which enables Flux to communicate with any kind of software. It can be coupled to other simulation software to model the interaction with CFD, system simulators, mechanical… This connection can be direct or driven by the MpCCI technology.

Powerful mesh generator: An easy but flexible mesh generator

The Flux mesh generator provides different mesh types and meshing technologies that can be mixed in both 2D and 3D situations: ▪ Triangular / tetrahedral elements obtained by Delaunay

type or advancing front method algorithms ▪ Quadrilateral / hexahedral elements generated through

either mapped or extrusive meshing

It offers powerful features that help the user to quickly get a precise mesh: ▪ Smart automatic mesh generation based on geometry ▪ Fine manual control of mesh size and distribution ▪ Linked mesh between identical geometric entities ▪ Import of already meshed and parameterized objects

Advanced physical properties for high performance calculations

A full range of physical models to simulate the low frequency behaviour of electromagnetic devices.Magnetic: ▪ Static, steady state AC magnetic, transient ▪ Circuit and mechanical couplings

Electric: ▪ Electrostatic, conduction
