A 2D axisymmetric model of the hydrogen plasma in a Microwave Plasma Chemical Vapor Deposition (MPCVD) system is implemented in COMSOL Multiphysics using the high frequency Maxwell solver and the heat transfer solver. Funer's model is calibrated based on experimental observations. The fractional electron energy loss is determined using BOLSIG+, a Boltzmann equation solver for electrons in weakly ionized gases under a given local electric field.

Thanks for the work. I have downloaded the files and read the reference paper. But, I don't understand the part - "Coefficient Form PDE" in the file named 'MPCVD_app.mph'. I'm curious about its physical meaning and its function. I would be very grateful if someone could answer my confusion.

Thanks for sharing the files. It means a lot for the young scientists or new users of comsol.

can you give me some guidance on what physics interface i should use to simulate the powder spheroidization process in inductively coupled plasma (ICP)
Thank you
