Simulating an expanding plasma plume

Please login with a confirmed email address before reporting spam

Hello,

There are two ways (at best of my knowledge) we can simulate the expanding plasma plume due to the irradiation from a laser on a target.
1. Particle tracing module
2. Fluid model.

We are working on the particle tracing module. In which we wish to release the particle with a half maxwellian velocity distribution profile. So we need to enter the velocity parameters vx, vy and vz.

I know the formulae for maxwellian velocity which is in the form:
f(vx) = (m / 2*pi*K*T)^(3/2) * exp(-m*vx^2 / 2*K*T),. Similarly f(vy), f(vz). T which we are using is 1ev = (approx.) 10^4 K.

To make it half maxwellian we need to use vx > vb,
So how do we do this?
