Plasma Modelling with COMSOL Multiphysics version 4.0a

Thursday 17 June 2010
10 a.m. BST (Central Europe 11 a.m., East Coast US 5 a.m.)

Modelling non-equilibrium discharges self-consistently has proved to be a significant challenge for the scientific community over the last three decades. The complexity of plasma modelling lies in the fact that it combines elements of reaction engineering, fluid mechanics, physical kinetics, heat transfer, mass transfer and electromagnetics. The net result is a rather complicated multiphysics problem.

The COMSOL Multiphysics Plasma Module is designed to simplify the process of setting up a self-consistent model of a low-temperature plasma.
The webinar will walk you through the process of developing a model of an inductively coupled plasma, as well as showing various other application-specific examples.

I wrote a letter to Comsol last year on this very subject, asking them if their multi-physics approach included analysis methodologies based on or similar to Anthony Peratt's textbook and its formulas and applicability (which in turn is based on his being a close colleague of Hannes Alfvén, and heeds Alfvén's 1970 warning about using his conventional MHD equations in cosmic plasma analysis and simulation). Peratt used particle-in-cell simulation methods on their 1980 supercomputers at Los Alamos, but I think there are more efficient ways to code and simulate cosmic plasma today. I have not received the favor of their reply, to date. It probably puzzled them.

I hope that Comsol's system can do this, although they have not responded to the cosmic plasma issue so far. I do not know if this webinar simply uses MHD type simulation, although in my experience Comsol are smart enough to succeed at almost anything they want to try in numerical simulation. They are used all over the world, with great success, in many industries. AStronomy is not one of those as far as I know. We are in dire need of being able to generate numeric simulations which can help support plasma phenomena as the EU ideas have them.

Can it be "demonstrated" that a large z-pinched filament can generate enough heat and pressure to create a plasmoid that seeds a star? Can Comsol's physics demonstrate Marklund convection in an magnetized plasma? Can it successfully integrate gravity dynamics with electromagnetic forces and show the self-forming ability to create sheaths and to demonstrate magnetic field discharge at the scale of a supernova?

If yes, I'd really like to know about it.
