In this model of a single-beam optical trap, SiO2 nanospheres in streaming water pass by or get captured depending on where they are released from. The electromagnetic force on the particles is calculated in the Electromagnetic Waves, Frequency Domain interface, with a Gaussian ... 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
This model demonstrates the use of the Two-Phase Thin-Film Flow, Phase Field multiphysics coupling, which can be used to predict the evolution of an interface between two different, immiscible fluids in thin, narrow channels. The example here presents a free boundary lubrication ... 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
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
This tutorial model demonstrates the use of the Area Scaling Factor (ASF) in the Heat Transfer in Shells interface, 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 ... En savoir plus
This tutorial shows how the displacement field of a deformed surface can be fit to a Zernike polynomial basis. The method of linear least-squares fitting is made significantly easier when fitting to an orthonormal basis, such as the Zernike polynomials on a circle. The displacement ... En savoir plus
Gradient-based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ...
