InCa3D

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.
