Simulation of arc-wire additive manufacturing is under development in many academic and industrial sectors and at different scales. The study at the melt pool scale is often interesting to study deposition shapes and defects but not very relevant to calculate the stresses and strains at ... En savoir plus

High average power lasers are currently being designed for laser fusion applications. Single beamlines with laser amplifiers should be able to deliver up to 10 kW average power at 10-Hz repetition rate. For achieving a 5 to 10 % wall-plug efficiency, this means that at least, 50 kW will ... En savoir plus

In India, more than 150,000 people are killed each year in traffic accidents, according to the Ministry of Road Transport and Highways 2016 report. That’s about 400 fatalities a day, which is far higher than in developed auto markets like the US which, in 2016, logged about 40,000 a ... En savoir plus

微磁学仿真(micromagnetics simulation)是自旋电子学与磁学领域中重要的一种重要的研究手段，本质上通过求解Landau-Lifshitz-Gilbert（LLG）方程来对磁性体系中磁矩的动力学进行仿真。微磁学仿真的主流软件以开源为主，包括OOMMF、Mumax3等，然而其在工程上的应用以及与多物理场耦合的扩展性仍有所不足。我们基于COMSOL的Physics Builder创立了微磁学仿真模块，不仅能够实现已有的微磁学仿真功能，还能够与COMSOL内置的多物理场进行耦合，如磁弹耦合、磁光耦合、各向异性磁电阻等，为学术研究和工程应用提供了新的接口 ...
