InCa3D is asimulation tool dedicated toelectrical connection modelling for both:

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

The software employsfinite element analysis based on the PEECPartial element equivalent circuit method^[3] which proved to be efficient to solveMaxwell's equations in low and middle frequency, thanks to its ability to convert interconnections geometry into equivalentRLC circuit,^[4] thus avoidingpolygonal meshing of the air around the device.

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

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.
