Tải COMSOL Multiphysics là một phần mềm mô hình số tiên tiến, đa mục đích để sử dụng trong mô hình hóa và mô phỏng các vấn đề dựa trên vật lý. Mục Lục Nội Dung. COMSOL Multiphysics.Jul 04, 2017 · For their analysis, the researchers created a COMSOL Multiphysics model to analyze laser beam-matter interaction in SLM. The model geometry consists of a simple cubic metal powder layer, resting on top of a large base plate that is exposed to a Gaussian laser beam . About COMSOL. COMSOL is a global provider of simulation software for product design and research to technical enterprises, research labs, and universities. Its COMSOL Multiphysics product is an integrated software environment for creating physics-based models and simulation applications.
Apr 13, 2015 · We will demonstrate how to model the absorption of the laser light and the resultant heating for a material with temperature-dependent absorptivity. The Beer-Lambert Law and Material Heating When light is incident upon a semitransparent material, some of the energy will be absorbed by the material itself.

Typical applications can involve rapid heating or cooling of a porous medium using a hot fluid, or internal heat generation in one of the phases (due to inductive or microwave heating, exothermic reactions, etc.) This phenomenon is observed in nuclear devices, electronics system, or fuel cells, for example. View screenshot » The COMSOL 4.0a product family includes these modules, including the all-new Batteries and Fuel Cell With the multiphysics capabilities of COMSOL Multiphysics, you can couple simulations with...COMSOL Multiphysics® is a general-purpose software platform, based on advanced numerical With COMSOL Multiphysics, you will be able to account for coupled or multiphysics phenomena.distribution deposited on the surface by the laser is assumed Gaussian. The temperature distribution is computed in the component using the Heat Transfer module in COMSOL Multiphysics®. The very short deposition of the energy is modelled using a time-dependent function that releases the energy during the pulse only. An important feature Laser ablation or photoablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma. Mar 16, 2020 · For a LP laser, only those born in the polarization plane can be injected. The color map represents the transverse laser field of E x in the (x, z) plane and E y in the (x, y) plane, respectively. (b) Particle tracking with static fields from PIC simulation in the CP laser case. The orange dots represent the initial positions for the trapped ...
