This example solves for the temperature distribution inside a vacuum flask holding hot coffee. The main purpose is to illustrate how to use MATLAB functions to define material properties and boundary conditions. En savoir plus
The electric shielding boundary condition is meant to approximate a thin layer of highly conductive material that provides an additional current path tangential to a boundary. This example compares the electric shielding boundary condition to a full-fidelity model and discusses the range ... En savoir plus
The contact impedance boundary condition is meant to approximate a thin layer of material that impedes the flow of current normal to the boundary, but does not introduce any additional conduction path tangential to the boundary. This example compares the contact impedance boundary ... En savoir plus
This is a benchmark model for an axisymmetric transient thermal analysis. The temperature on the boundaries changes from 0 degrees C to 1000 degrees C at the start of the simulation. The temperature at 190 s from the anlysis is compared with a NAFEMS benchmark solution. En savoir plus
This model couples the Navier Stokes equations and the heat transfer equations to examine density driven flow of free fluids. Here the fluid is in a square cavity with a heated wall. The buoyancy force is a Boussinesq term added to the Navier-Stokes equations. The equation is ... En savoir plus
Diesel particulate filters (DPFs) are designed to remove and filter soot (diesel particles) from the exhaust of diesel engine vehicles. The filters in such systems are typically structured with long, air-filled channels surrounded by a porous medium that retains the soot. Although the ... En savoir plus
This tutorial demonstrates how to model the band-to-band tunneling across a p–n junction. The tunneling effect is imitated by defining the User-Defined Recombination domain feature which makes the electrons disappear from the conduction band on the n-side and holes disappear from the ...

Non-isothermal non-Newtonian flow in an internal mixer for rubbers and polymers. The Carreau model is used including thermal effects for the viscosity. En savoir plus
This example demonstrate two-phase flow in a porous medium which contains a low permeable lens. The heavier phase infiltrates the porous medium, so the low permeable lens is infiltrated only when a critical saturation at the outside is reached. En savoir plus
Vibration and noise in washing machines, due to the non-uniform distribution of clothes in the barrel, is a common problem worth studying and optimizing for. This model simulates a multibody dynamics model of a horizontal-axis portable washing machine. An eigenfrequency analysis is ... En savoir plus
