This tutorial uses an equivalent circuit approach for modeling the performance of a lithium-ion battery, requiring no knowledge about the internal chemistry or structure of the battery. A 0D equivalent circuit battery model is defined based on a resistor connected in series with a ... En savoir plus
A ribbon mixer (sometimes referred to as a ribbon blender) is a mechanical device that is commonly used to mix different types of granular material. Ribbon mixers are widely used across various industries including food processing, pharmaceuticals, chemical industries, agriculture, ... En savoir plus
This example exemplifies how to compute the design sensitivities of your COMSOL Multiphysics® model. A more detailed description of the modeling process can be seen in the blog post "Computing Design Sensitivities in COMSOL Multiphysics". En savoir plus
The model used is the P2D model also called the Newman model. Parameter estimation is run using experimental data of driving cycles from healthy cells. The parameter values are determined for a confidence of 0.95 for each parameter. Parameter estimation is then run using data from ... En savoir plus
This model shows how to simulate moisture redistribution inside a wall with capillary active interior insulation. The wall consists of three layers: brick, mortar and insulating material. At the beginning of simulation, there is a sudden change in vapor pressure and temperature at ... En savoir plus
Mechanical precession prevents bicycle pedals from falling off. The model captures this effect using a multibody dynamics simulation together with a contact analysis. A friction coefficient is associated with the contact in order for the model to capture the effect. En savoir plus
The purpose of this model is to demonstrate pure rolling of a rigid wheel when given an initial forward velocity together with a prescribed lean about this direction. It is assumed that the the rolling motion of the wheel is not affected by contact such that all three components of the ... En savoir plus
Learn how to combine imported CAD with STL meshes in COMSOL Multiphysics® using an example of a dental implant. The STL mesh is prepared in a Mesh Part, the imported CAD assembly is prepared in the Geometry sequence, and the two are combined in a Mesh-Based Geometry sequence. ... En savoir plus
PCB is fabricated by laminating multiple materials, such as FR-4, copper, and resin, which exhibit significantly different coefficients of thermal expansion (CTE). When subjected to heating, the differential thermal expansion among these layers induces interlaminar deformation mismatch, ... En savoir plus
A small building block of integrated photonics, i.e., a Silicon-on-Insulator taper, is considered. For a larger system design, it might be useful to determine the phase delay such a device introduces. Here, we showcase the layout needed to do it in COMSOL, including a proper Port ...
