Parameters

rv  Double
Reduced variable rv = D*t/r², where D is the diffusion coefficient, t is the time and r is the radius of the cylinder.
rz  Double
Reduced variable rz = D*τ/r², where D is the diffusion coefficient, τ is the time constant of the outer concentration change, and r is the radius of the cylinder.

Return Value

ValueTupleDouble, Double, Double
