Effects of underfill material on solder deformation and damage in 3D packages
… examine the effects of the introduction of a periodic boundary condition and the presence of underfill material on the stress and strain fields and evolution of failure of an FEA model that is representative of a solder joint in a 3D IC package. The model solder joint is placed between two …

First-principles approaches for accurate predictions of nanostructured materials
… metal oxides on approximations in DFT and the periodic boundary condition.

On the boundary conditions for dissipative particle dynamics (DPD)
… virtually no density fluctuation near the wall boundary. Two test cases of Couette flow and lid driven cavity have been done to show that DPD can be used successfully to validate the results. In order to simulate flows where periodic boundary condition cannot be applied, a source-sink method is …

Analysis of periodic structures using finite-difference time-domain method
Periodic structures are of great importance in electromagnetics these days due to their wide range of applications such as frequency selective surfaces (FSS), electromagnetic band gap, periodic absorbers, metamaterials and many others. The aim of this work is to develop several algorithms to …

Lattice Vibration Study Of Silica Nanoparticle In Suspension
… by water molecules has been performed. Periodic boundary condition has been used in all three directions. The effect of nanoparticle size and temperature of system on the thermal conductivity of nanofluids has been studied. It was found that as the size of nanoparticle decreases thermal …

Quantum Monte Carlo: Applications of the Twist -Averaged Boundary Conditions and the Calculation of Forces
… with a small system in a super cell geometry. Periodic boundary condition is commonly used in such a setup which leads to large and fluctuating finite size error. Twist-averaged boundary condition (TABC) averages over all the possible twist angles in the boundary condition and could …

Prediction of Aerodynamic Noise Generated By Wind Turbine Blades
… rotating reference frame method at steady state conditions which resulted in predicting the flow field accurately with less computational time. The rotational periodic boundary condition with 1800 symmetry has been used with which one blade has been simulated instead of two. This reduced the mesh …
