a dedicated software

to analyze current distributions, compute radiated magnetic field or evaluate stray inductances

Easy control for each parameter

Parametric control in InCa3D allows the control of all geometry, electrical properties and excitation source values.
The use of such parameters which can be simple real numbers but also mathematical expressions dramatically simplifies geometry creation, modifications and re-use.
Thanks to this parametric description, InCa3D turns out to be a great help for innovation by making easier the testing of new topologies.

Quick and robust solver

Based on years of experience in the domain of software development and relying on efficient numerical methods, set up in collaboration with research teams (G2Elab), CEDRAT provides with InCa3D a highly valuable tool combining fast and precise computations.
Compared to finite element methods which are the reference in the domain of electrical engineering, the semi analytical method used by InCa3D turn out to be more adapted to the simulation of systems of conductors.

Extended post-processing capabilities

InCa3D will compute quantities which are hardly measurable like the current density, the forces induced by the current flow, losses etc.

Besides, InCa3D makes it possible to compute equivalent impedances, and especially stray inductances which are often an essential characteristic of interconnections systems.
The range of post-processing results available enable for the designer to proceed to real virtual prototyping and thus reduce development costs.


Coupling to system simulator

In addition to the set of post processing results directly accessible in the software, InCa3D allows the export of results to system simulators like Portunus, Saber, Spice and in the Modelica and VHDL-AMS languages. The equivalent impedance matrix provided by InCa3D can be imported directly as a macro component and included in a complete electrical circuit allowing for more detailed investigations.


Import and de-featuring of MCAD files

  • Accepted formats: STEP, IGES, SAT, CATIA (v4 and v5) and Pro/E
        . The simulation of complex structures (power modules, distribution bars or switchboards) is thus very simple and fast
  • Possibility to clean up or heal automatically the imported files
    . Save a lot of  computation time and memory resources without loosing accuracy
  • Creation of unidirectional conductors from one or more imported volumes thanks to a new algorithm
       . Very useful to model cables or PCB bond-wires
  • New predefined conductor profiles are available (circular full, circular hollow and rectangular hollow sections)

Images-based conductor creation

  • Accepted formats: BMP, GIF, JPG, PNG and TIF
       . Draw easily at the real size one part or the totality of the structure to simulate

Parametric solving

Perform multiple parametric solving by means of an extended scenario definition

  • Help engineers to find the optimized values for some parameters or key-properties of the considered system (the position of some conductors, the shape of their cross-section or the amplitude of the power supply sources) 
  • Plot 2D curves showing the evolution of the output quantities in function of the parameter to optimize

Impedance export

  • Create and connect automatically the minimal number of impedance probes necessary to measure all the desired impedances
       Easier to export towards external circuit simulators an equivalent macro-component of the structure

  • Possibility to export an equivalent circuit into the VHDL-AMS format
       The inclusion of InCa3D models into system-level simulators, like Portunus, is more robust and efficient
