Magnetic fieldCOMSOL MultiphysicsPea proteinsFinite element analysisTo address the dilemma of inefficient plant protein electrostatic separation, some optimization strategies were proposed by combining experimental analysis with COMSOL Multiphysics simulation. Micronized pea powder was obtained by airflow impact ...
Simulation results for the magnetic flux density in the Vector Hysteresis Modeling tutorial. What if your material model includes nonlinear expressions that are impossible or very difficult to express in terms of standard variables or additional partial differential equations (PDEs)? Version 5.2 of COMS...
The Research of Magnetic Field Simulation System Based on COMSOL Multiphysics simulation software COMSOL which used in this paper is mainly focused on the simple electromagnetic field, variation of the electromagnetic field simulation, and the rotor Halbach static magnetic field: a outward flux focusing...
磁体中的磁矩动力学可以通过微磁模型描述,即朗道-栗弗席兹-吉尔伯特方程(Landu–Lifshitz–Gilbert equations,LLG)。我们使用 COMSOL Multiphysics®软件中的“物理场开发器”开发了一个定制的“微磁模块”,可用于在 COMSOL®软件框架内进行微磁建模。这个定制的微磁模块可以直接与其他附加模块耦合进行多物理场微磁仿真...

The Rotating Machinery, Magnetic interface solves Maxwell’s equations to compute the distribution of the electromagnetic field. Most quantities of interest (e.g., the applied torque) can be computed once the fields are known. In time-dependent ...
As an example, let’s consider a loudspeaker. We could measure just the magnetic field in the voice coil in a single-physics model, but it may be more useful to also study how the magnetic field interacts with the other loudspeaker components to create force and vibrations. Using COMSOL Mul...
