Comsol，Inc。是工程模拟软件的全球领先提供商，宣布发行ComsolMultiphysics®4.4，这是其强大的电气，机械，流体和化学应用模型和仿真的功能强大平台的最新版本。
New COMSOL Desktop Interface for Windows® Offers Enhanced User Experience
A ribbon design has been introduced to the COMSOL Desktop® environment, when run on Windows® platforms, to provide easier navigation and an enhanced user experience. By grouping commands and displaying them as needed, the ribbon makes it easier to find and use the tools to let you get your work done faster. Commands are grouped and ordered according to the main modeling tasks, which are themselves grouped under dedicated tabs for definitions, geometry, physics, mesh, study, and results. COMSOL Desktop brings several additional workflow improvements such as a one-click select feature that enables faster selections in the graphics window. Using this feature, users can now hover over a boundary or domain to highlight it, and then select it with a single click. Another noteworthy feature is a new auto-complete search function that allows you to quickly find the postprocessing variables you need, among the many that are created when working with multiphysics models.
Comsol AB首席技术官Ed Fontes说：“ Comsol 4.4中的新用户界面通过以结构化的方式概述了所有物理和功能，从而提供了出色的可用性和指导。”“功能区为用户提供了建模过程的工作流程的清晰图片，帮助他们快速，轻松地确定所涉及的每个步骤可用的功能。”
新的多物理耦合功能与多物理节点
现在，在模型树中可以使用一个全新的多物理节点，从而实现了多物理模型的简化设置。它使用户可以通过从相关的多物理耦合列表中选择单物理接口的组合轻松扩展。“成为模拟多物理应用程序的领导者多年的领导者已导致comsol开发了这种管理模型工作流程的方法，” Comsol，Incol Inc.产品管理副总裁Bjorn Sjodin说：“多物理节点为您提供了可用耦合的全面概述在您的模型中。然后，您可以通过确定模拟中包含的物理学如何相互作用来控制如何考虑多物理现象。”
引入混音器模块
The new Mixer Module, an add-on to the CFD Module, was designed specifically for the analysis of stirred mixers and reactors used in the manufacturing of pharmaceuticals, food, fine chemical, and consumer products. With its dedicated features for simulating mixer and impeller designs, as well as concentrations, velocities, and temperature profiles, the Mixer Module is ideal for accurately modeling a variety of industrial processes. The Mixer Module expands on the rotating machinery capabilities of the CFD Module by providing features for the simulation of turbulent and laminar flow, Newtonian and non-Newtonian fluids, free surfaces, non-isothermal flow, and reacting flow. The Mixer Module provides results on a number of quantities specific to mixing, such as mixing efficiency, power draw, and the impeller pumping number.
New Functionalities in COMSOL 4.4
Comsol Multiphysics 4.4还为该软件的现有功能引入了各种增强功能。Comsol，Inc。首席执行官Svante Littmarck说：“ Comsol致力于提供可靠，直觉的模拟工具，以支持创造力并节省宝贵的开发时间。确保用户可以以最高的精度来验证和优化其设计。”这些改进在整个产品套件中提供了提高的性能和可用性：
几何和网状-核心功能增强功能包括用户定义的几何原始素的新几何子序列，if/else statements in the model tree for geometry creation, and mesh export to NASTRAN® file formats.
