InCa3D is a simulation tool dedicated to electrical connection modelling for both:

  • Electromagnetic compatibility[1][2]
  • Power electronics

The software employs finite element analysis based on the PEEC Partial element equivalent circuit method [3] which proved to be efficient to solve Maxwell's equations in low and middle frequency, thanks to its ability to convert interconnections geometry into equivalent RLC circuit,[4] thus avoiding polygonal meshing of the air around the device.

InCa3D is developed in France (in collaboration with G2ELab) and distributed by Altair Engineering Inc.[5]

Main application fields

InCa3D is well suited for modelling the behaviour of various connectors,

  • from ICs, small wire bonds and PCBs tracks,
  • up to bus bars, power modules and large distribution switchboards.
