Presently, we have demonstrated our results for a wide range of plasma parameters, ranging from nonideal gaseous state to strongly coupled range. It is noted that the extended HNMED method is excellent for lower system sizes with constant external force field strength, where signal-to-noise ratio is acceptable for

Plasma thermal conductivity of SCCNPs system was computed over a suitable domain of plasma couplings (1 ≤ Γ ≤ 300) and screening strength (1.5 ≤ κ ≤ 4) by employing constant external force field strength through HNEMD approach. It is shown that our HNEMD outcomes are in reasonable agreement with the earlier outcomes measured from EMD, HNEMD, InHNEMD, HPMD, and VP approaches for SCCNPs. New computations show that the minimum values of thermal conductivity exist at same values of plasma coupling Γ and it shifts toward higher Γ with an increase of screening κ, as expected in earlier numerical approaches. It has been revealed that the plasma thermal conductivity depends on plasma parameters (Γ, κ) in 3D complex dusty systems that illustrate earlier results of SCCNPs. In this study, the HNEMD method is a mostly dominant numerical approach, which occupies fast computations of plasma thermal conductivity, for small to intermediate system sizes. This chapter provides the understanding and investigation of nonlinear regime of the SCCNPs for a suitable low value of external force field strength. In future, thermal conductivity of complex plasma can be calculated by applying external magnetic field or an electric field strength and it can be applied to other
