Frame Fatigue Life

The application allows you to evaluate the fatigue life in a frame with a cutout. You can modify the cutout geometry and test different load types and materials. The geometry is automatically updated once you modify the input parameters. When you click Solve, the application firstly performs the necessary checks in order to verify that all inputs are correctly specified, and then it evaluates ...

1D Lithium-Ion Battery Model for Internal Resistance and Voltage Loss Determination

This tutorial digs deeper into the investigation of rate capability in a battery and shows how the *Lithium-Ion Battery* interface is an excellent modeling tool for doing this. The rate capability is studied in terms of polarization (voltage loss) or the internal resistance causing this loss. A typical high current pulse test, namely a Hybrid Pulse Power Characterization (HPPC) test, is ...

Parameter Estimation for Nonideal Reactor Models

Real reactors can be modeled as combinations of ideal reactors. In this example the so-called "Dead zone model" is utilized. Two ideal CSTRs with interchange are set up to model the real reactor. One CSTR represents the highly agitated region and the other the less agitated region. For this, two parameters relating the volume and exchange rate of the two regions need to be found by comparing ...

Outgassing Pipes

This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature.

Mixed Diffuse-Specular Radiation Benchmark

This model shows how to use the Mathematical Particle Tracing interface to simulate mixed diffuse-specular reflection between surfaces in an enclosure. This model is separated in two parts. The first part compares the heat fluxes computed by the Mathematical Particle Tracing interface with the exact solution for two identical infinitely long parallel grey plates under mixed diffuse-specular ...

Water Purification by Silver Complexation

Many industrial processes leave remainders of toxic dissolved metal ions in process flows. A common method for removing metal ions from water is complexation. This model example shows a purification reactor where silver ions are complexated to diamine-silver for removal. Ammonia (L) is added across a membrane in a tubular reactor in order to remove silver ions (M) from a water stream. A metal ...

Corner Cube Retroreflector

A corner cube retroreflector can be used to reflect rays so that their reinitialized trajectories are parallel to their initial trajectories, regardless of the angle of incidence. This tutorial model shows how to simulate the reflection of a bundle of rays at a cube corner retroreflector using the Geometrical Optics interface.

Designing a Waveguide Diplexer for the 5G Mobile Network

A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands will show the diplexer characteristics in the Ka-band.

Electrode Growth Next to an Insulator

This example shows how to model secondary current distribution and electrode growth with a moving geometry. To avoid numerical instabilities, a seed layer is introduced in the initial geometry to obtain a right angle at the edge between the growing electrode and the insulator.

Creating a Phase Envelope with a Multicomponent Flash Calculation

* A flash calculation is an equilibrium calculation of a system where several components (species) and phases are present at the same time. This is a demonstration how to use the thermodynamics interface to make flash calculations from data provided external thermodynamic databases. The system in this model is Methane/Ethane/Propane, which would require 3D surfaces to plot the phase envelope. ...
