This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. En savoir plus
This model demonstrates how to couple the Radiative Beam in Absorbing Media interface to the Radiation in Absorbing-Scattering Media interface. To learn more about this model, see our accompanying blog post “Modeling Absorption and Scattering of Collimated Light”. En savoir plus
This model demonstrates the caustic effect produced by a cylindrical mirror. It highlights the advantages of the forward ray shooting method when modeling specular reflections from an external radiation source with the Surface-to-Surface Radiation interface. En savoir plus
This tutorial model demonstrates the use of the features for heat transfer in layered shells, to account for the curvature of the layers when applying heat fluxes and heat sources. The results obtained with the Heat Transfer in Shells interface applied to a boundary (with extra ... En savoir plus
When radiation occurs across a very narrow gap this is often well-approximated as radiation between infinite parallel plates. This model considers three aluminum plates separated by narrow air gaps. The model compares the classical approach, based on the Surface-to-Surface Radiation ... En savoir plus
This tutorial shows how to simulate coupled heat and moisture transport in a wall made of a load bearing and an insulation layer. Moisture and temperature conditions vary with time on both sides of the wall and rain loading is included. The 1D model is a benchmark test defined in ... En savoir plus
Many important processes in the mesoscale can be described by phase-field models. One of the oldest phase-field problems is the spinodal decomposition. Several standardized benchmark problems have been developed by the phase-field community. In this entry, these problems are solved using ... En savoir plus
Rayleigh-Bénard's convection cells is a classic in fluid dynamics. We present here two different approaches for computing the critical Rayleigh number above which the cells form. En savoir plus
Tesla microvalves exploit the non-linear nature of inertial flow to create anisotropic flow resistance. They can be used as robust valves owing to their passive working mechanism, but for many applications the diodicity is too low. Two-dimensional simulations and optimization over ... En savoir plus
In this model, the packing behavior of grains is simulated using three force models: Hertz-MD, Hertz-MD with adhesion, Hertz-MD with adhesion and van der Waals forces. The packing efficiency is calculated to quantify the extent of packing observed. En savoir plus
