Lithium iron phosphate (LFP) is a common positive electrode material in lithium-ion batteries. Specific for the LFP electrode material is that its equilibrium (open circuit) potential, when defined as a function of the lithiation state, features a large flat plateau with a more or less ...

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in PTC Pro/ENGINEER® by using the LiveLink™ interface. En savoir plus
This model simulates a holographic page data storage system. The studies include the recording and retrieval processes. The object beam encrypting 8-bit data is focused into a holographic material by a Fourier lens (Fourier transformation). In the recording process, the object beam ... En savoir plus
This example exemplifies how you can export the data from your mesh and results to a text file. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Exporting Meshes and Solutions Using the Application Builder". En savoir plus
An interesting question was raised in the 1950s by the mathematician Ernst Straus that, in an arbitrarily shaped empty room with side walls made of perfect mirrors, will a point light source always illuminate the whole room? This question was answered by the Nobel Prize-winning ... En savoir plus
Find the optimal cross section areas of trusses in a structure given a prescribed set of limitations and a clear objective. The structure is made up of trusses which are elements that can only sustain axial forces. En savoir plus
This model shows the workflow to define a transfer orbit trajectory with user defined orbit option. The direct solar, albedo, and Earth radiative thermal loads are analyzed during the transfer from low Earth orbit to geostationary orbit. En savoir plus
When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... En savoir plus
Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care ... 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 ...
