NEi Software разрабатывает дополнительные возможности для FEMAP
Компания NEi Software (ранее Noran Engineering Inc.) в дополнение к распространению продукта FEMAP от Siemens PLM Software, внедряет в него дополнительные функции и сервисы. Посредством интеграции FEMAP с NEi Nastran, NEi Software предлагает пользователям расширенные возможности, особенно для решения сложных задач, связанных с расчетами композитных материалов.
FEMAP v9 от Siemens PLM Software является пре- и пост-процессором, независимым от используемого CAD-пакета и солвера. FEMAP используется инженерными компаниями по всему миру для моделирования различных конструкций, изделий, продуктов, процессов и систем. Графичекий пользовательский интерфейс (GUI) предоставляет полный доступ ко всем возможностями FEMAP. Тесная интеграция с NEi Nastran позволяет использовать дополнительные возможности, в особенности для моделирования укладки композитов.
FEMAP v9 также предоставляет дополнительные возможности работы с деревом модели в области приложения граничных условий, использования API-утилит путем панели инструментов пользователя. Обеспечена интеграция с широким спектром наиболее часто используемых в промышленности решателей задач прочности и термоупругости.
В число инструментов FEMAP дополнительно включены:
- критерии разрушения Puck и LARC02, разработанные ранее специально для NEi Nastran;
- возможность "анализа на основе концепции прогрессивного разрушения слоев композита" - Progressive Ply Failure Analysis (PPFA)TM для моделирования прогрессивного разрушения, наступающего за разрушением первого слоя (first ply failure);
- инструмент Automated Impact Analysis (AIA) для моделирования дроп-тестов и других задач явным методом;
- инструменты Automated Surface Contact Generation (ASCG) и Automated Edge Contact Generation (AECG), которые могут быть полезны при решении задач для больших оболочечных конструкций, в частности, в кораблестроении и автомобильной промышленности.
What FEMAP Is
FEMAP by Siemens PLM Software is a professional level pre- and postprocessor used for setting up models for analysis and viewing the results of engineering simulations for structural, thermal, and fluid problems. It can import geometry from all major 3D CAD systems and uses a variety of finite element analysis (FEA) and computation fluid dynamics (CFD) solvers to obtain solutions and results.
Designers, engineers, and analysts rely on FEMAP to gain the technical insight they need to assure the quality of their designs — ranging from simple linear static analysis to advanced multiphysics solutions. FEMAP is used to simulate everything from simple solid parts to complex assemblies and full systems.
FEMAP has been applied to well-known, high-profile projects, in a wide variety of industries including aerospace, automotive, maritime, petroleum, medical, and consumer goods. Users benefit from reduced product development costs, improved physical testing processes, and quicker time to market.
FEMAP V9.3 Features
Version 9.3 of FEMAP from NEi Software offers geometry import/export, specifically CATIA import with a new direct CATIA v5 translator; IGES import; IGES export, specifically Parasolid; and import of VDA, I-deas, Pro/ENGINEER, Solid Edge v19, and Unigraphics, and others.
FEMAP V9.3 offers a new method of applying loads through data surfaces, a composite layup modeling interface, and enhanced geometry manipulation tools. New icons and toolbars add greater flexibility to the modeling process, and an expanded Model Info tree encompasses more functionality at the top level.
FEMAP V9.3 enhancements include new composites layup dialogs; 1D and 2D data surfaces; a model info tree for load and constraint definition; project nodes; merge nodes; new entity picking methods; and other user interface enhancements.
FEMAP V9.3 also offers a postprocessing contour display: Through the group functionality, all contour styles (i.e., contours, criteria, beam diagrams, iso-surfaces, section cuts, contour vectors, etc.) can selectively be displayed or not, allowing FEMAP to display partial results on a model. This allows you to define where you wish to see the results while leaving the remainder of the model visible, but not contoured.
Miscellaneous enhancements include support for the Patran neutral file, and all geometric entities can be migrated from Patran into FEMAP, including named components or groups. Plus, the facility to check element distortion using the Jacobian approach has been added as well as improved support for the 3Dconnexion Space Navigator devices. Finally, the FEMAP material library has been extended to include more than 240 material definitions.
Geometry creation includes create point, line, circle, spline, surface, volume; Boolean and extrude/revolve solid modeling; mid-surface extraction and extended surfaces; project curves onto surfaces; and more. Other new capabilities include various functions under meshing, element library, materials, loads and constraints, groups and layers, results processing, solution capabilities, analysis set manager, user interface, graphics, and customization.
Version 10 on the Horizon
FEMAP is for product design and development professionals who have moved beyond typical in-CAD simulation software or more limited FEA products. By procuring FEMAP from NEi Software, users gain NEi Software’s live technical support from a staff of experienced analysts, offering what the company says is “the best FEMAP Nastran training in the industry with eTraining and local classes across the U.S.”
Julia Oien, who is VP of Sales for North America at NEi Software, says, “The aspect I find particularly gratifying in working with our FEMAP customers is knowing that NEi Software's support will be a significant and very much appreciated ingredient in their initial and ongoing success. NEi Software's long history with FEMAP providing application assistance, technical support, training classes, and consulting has allowed NEi to develop an organization that enables us to mentor our customers so they get the most from simulation, digital prototyping technology, and their software investment.”
NEi Software says that FEMAP Modeler Version 10 is “coming soon.” It will be the latest release of the finite element modeling pre- and postprocessor application known for its tight integration with the Nastran solver. The v10 release focuses on core simulation tasks, including preprocessing and meshing. New tools are provided for meshing complex structures more accurately, verifying mesh integrity and accuracy, and optimizing the mesh to efficiently capture the true structural response.
