AddPlasmaandAddPlasmaFlux, when in a radial geometry, the radial variation of the particle weight can be adjusted by the input parameterradial_numpercell_power. The particle distribution and weights are adjusted accordingly. Though, when the minimum radius,rmin, is greater than zero, the weights of the particles was not correct. The weights did not account for the fact that the particles before the transformation are generated only in the rangermintormaxwhereas the existing formula assumed that particles were created in the range 0 tormax(before transformation). The result is that fewer particles are generated than the weight is accounting for. Multiplying the weights by the factorrmax/(rmax - rmin)accounts for this difference.This addresses the issue raised in #6798.
