randKappa

randKappa

Create a random sequence distributed according to the general kappa velocity distribution, assuming three velocity components.

randKappa Parameters

sigmas (float): The widths of the distribution.

seed (integer): Random number seed.

lowerLimits (vector float): The lower limits for the velocities.

upperLimits (vector float): The lower limits for the velocities.

numberSequence (code block, optional): <NAFunc numberSequence> is an NAFunc code block that generates a random number; if not specified, Vorpal’s default random number generator (uniform in [0,1)) will be used to generate the initial random number.

Example randKappa Block

<NAFunc velocitySequence_2>
  kind = randKappa
  sigmas = [$0.8*SIGMA_VEL$ SIGMA_VEL $1.2*SIGMA_VEL$]
</NAFunc>
