Hello,
I am new in Ansys and need to know following : May i create nitrogen gas volume with N=10^3 ... 10^4 free electrons ? I need take into account every electron separately and every electron should have random position in the gap. So initial condition in the gas volume will look like sum of N Dirac's delta functions. After voltage appliance electron will produce separate avalanches which will grow and merge together. The next question if following : May i simulate barrier discharge with Ansys ? Is there a way to calculate charge distribution at the dielectric surface ? Regards Dmitry |

CFX does not have this built in. Can you define it using source terms?

I have no idea about the capabilities of Comsol.
The particle tracking model in CFX is not really suitable for this as particle tracking assumes the key forces on the particle are viscous forces. There is no viscous forces on electrons and the key forces now are electrical. I do not think CFX is going to be very useful for you if this is what you want to do. |
