View Factor Computation

When simulating surface-to-surface radiation, we rely on the view factors between elements of diffuse surfaces that emit and receive radiation. To compute surface-to-surface radiation in a given geometry, operators are created by the heat interface and can be used to evaluate view factors in postprocessing. This model shows how to compute view factors using the operators provided by ...

Isothermal HI Reactor

For a perfectly mixed reactor with a predefined constant temperature, the reacting system’s energy balance is not needed to describe the system behavior. The behavior is defined as the composition and the production or consumption of species over time. Furthermore, because the reactor is perfectly mixed, the Reaction Engineering interface can also set up a model even though it has no ...

Orange Battery

This tutorial example models the currents and the concentration of dissolved metal ions in a battery (corrosion cell) made from an orange and two metal nails. This type of battery is commonly used in chemistry lessons. Instead of an orange, lemons or potatoes can also be used.

Molecular Flow Through an S-Bend

This model computes the transmission probability through an s-bend geometry using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability by the two methods is in excellent agreement with less than a 1% difference. This model requires the Particle Tracing ...


This model shows how to compute the thickness of a thermally evaporated gold film. The thickness of the deposited film is computed both on the walls of the chamber and on the sample.

Heat Conduction with a Localized Heat Source on a Disk

This classical verification model solves the steady state temperature distribution in a plan disk heated by a localized heat source at its center. It shows and compare different ways to define a heat source localized on a small domain by representing it either as a geometrical point or a small disk. Both modelings have analytical solutions to which the obtained numerical results can be compared. ...

In-Plane Framework with Discrete Mass and Mass Moment of Inertia

In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared with the values given by an analytical expression.

Tapered Cantilever Gravity Load

This example shows a 2D plane stress model of a membrane with a thickness of 0.1 m. The load is a gravity load that acts in the negative y direction. The left end boundary is kept fixed. The resulting shear stress is compared to a NAFEMS benchmark value

Axisymmetric Cavity Resonator

This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and perfectly conducting walls. Analytical expressions for the eigenvalues can be obtained using separation of variables. ...

Split and Recombine Mixer Benchmark

This example models a split and recombine mixer channel in which a tracer fluid is introduced and mixed by multi-lamination. Diffusion is removed from the model using an extremely low diffusion coefficient so that any numerical diffusion can be studied in the lamination interfaces. The results compare well with Glatzel et al (Ref 1.) in both the lamination patterns and total pressure drop ...
