网格化分
LMS Virtual.Lab网络划分是对于几何修复,创建网格和针对采用工业标准求解器进行线性、非线性或碰撞有限元分析的最完整配置。该模块网格划分工具功能强大,结合了基本和高级的自动网格划分功能和相关的一些在线框、曲面或实体几何上生成有限元模型的功能。此工具具备了所有以网格为基础或以CAD为基础进行分析的必需功能。
LMS Virtual.Lab Meshing 网格划分
该模块是对于几何修复,创建网格和针对采用Nastran(MD、MSC、NX、NEi)、Abaqus、LS-DYNA和RADIOSS等工业标准求解器进行线性、非线性或碰撞有限元分析的最完整配置。
几何修复功能帮助用户确认导入的几何数据和改善对象的拓扑关系与几何属性。其功能包括通过指定容差或检查曲面之间的连接、锐边、曲率突变、薄表面和表面边界等是否存在错误。
该模块网格划分工具功能强大,结合了基本和高级的自动网格划分功能和相关的一些在线框、曲面或实体几何上生成有限元模型的功能。基于强大拓扑工具,原始几何的几何特征能自动简化以满足划分网格的要求,同时又不对原始几何产生影响。这样可以大量减少手工编辑单元的时间,从而减少了许多模型准备时间。自动划分网格条件下,用户可以通过控制网格大小、单元分布、网格类型、结点分布以及网格捕获公差等参数完全控制网格的生成。这些参数可以加快流程自动化,并确保与企业标准兼容。已划分网格的部分总是与原来的几何相关,能够自动反映出CAD模型的进一步修改。
对于特定应用,该模块有相应的更高级的网格划分方法。例如,在航空航天方面可能要求划分极其结构化的映射曲面网格,对内燃机模型等复杂结构划分为最小的、六面体占主体的混合实体单元,或者需要自动考虑不同零件间兼容性等。这些问题都可以在网格划分模块中找到量身定做的解决方法。
对于寻找支持多种有限元分析求解器前后处理工具的企业而言,LMS Virtual Lab Meshing是一个理想的标准配置。此工具具备了所有以网格为基础或以CAD为基础进行分析的必需功能。充分参数化的高级网格划分工具使与设计关联的分析具有可行性和应用性。由于取消了几何数据转化,工作小组将节省建立分析和执行典型迭代设计的时间。

Mitsubishi and LMS develop procedures that speed body NVH analysis up to a factor of 100
Mitsubishi Motor Corporation and LMS engineers have teamed up to deploy analysis procedures that reduce the time required to simulate the NVH performance of a car body to as little as one-hundredth of the time previously required. Conventional full-body finite element models that are normally used to evaluate body NVH prior take so long to solve that relatively few design alternatives can be considered.
Mitsubishi develops vehicle platform with support of LMS
Mitsubishi Motors Corporation is working with LMS in a strategic partnership to frontload vehicle engineering and optimize designs for critical attributes earlier in the process. LMS recently supported Mitsubishi in reaching these objectives on a new small-car platform with multiple upper body designs. Mitsubishi also teamed with LMS to deploy these advanced simulation processes based on LMS Virtual.Lab for the development of innovative future vehicles.
