  Hi, I was exploring the PIN MZ modulator example (https://optics.ansys.com/hc/en-us/articles/360042327854-PIN-Mach-Zehnder-modulator) example and I found that the thermal impedance of the eletrodes are set as 1000 m2K/W
  I wonder why is this value so large given that alumium has a large thermal conductivity (326 W/mK)? Thank you!

  Curretly this example https://optics.ansys.com/hc/en-us/articles/360042327854-PIN-Mach-Zehnder-modulator has only CHARGE simulation.
  Large thermal impedance is usually meant to be very long geometry.
