UGS объявила о выходе Femap v9.3

Ведущая в мире корпорация-разработчик PLM программного обеспечения UGS объявила о выходе новой версии пре/постпроцессора Femap v9.3, полностью интегрированного в NX Nastran разработки UGS. Новая версия продолжает двадцатилетнюю историю качественных изменений Femap, целью которых является улучшение работы инженеров-расчетчиков. «Одним из преимуществ Femap является широкая интеграция с Nastran», - говорит Бил МакКлур (Bill McClure), вице-президент UGS, - «новая версия Femap призвана еще больше расширить возможности взаимодействия с Nastran, а также улучшить возможности самой среды моделирования».

Femap всегда был сфокусирован на повышении удобства и производительности построения конечно-элементных сеток. Femap может напрямую использовать модели из большинства CAD-систем (Unigraphics NX, CATIA, Solid Edge), обеспечивает импорт/экспорт DXF, IGES, SLA,  ACIS, Parasolid данных. Одновременно с этим Femap поддерживает форматы наиболее широко используемых CAE-систем (ABAQUS, ANSYS, LS-DYNA, MSC.Software, NEi.Nastran).

UGS Releases Femap v9.3 for FEA

UGS Corp., a leading global provider of product lifecycle management (PLM) software and services, today announced the release of Version 9.3 of Femap software, the finite element analysis (FEA) component of the UGS Velocity Series portfolio.

Femap Version 9.3 is the latest release of UGS’ robust pre and post processor for engineering FEA. Femap is known for its tight integration with Nastran, in particular UGS’ own NX Nastran solver. This latest version of Femap continues a 20-year history of productivity and functionality improvements aimed directly at dedicated engineers and analysts.

“One of Femap’s strengths is its depth of integration with the Nastran solvers,” said Bill McClure, vice president, UGS Velocity Series. “This new release serves to significantly increase Femap’s support of Nastran functionality as well as expand user interface extensions and enhancements to modeling capabilities.”

Femap Version 9.3 enhancements add significant new modeling functionality and expand Nastran support and integration through the following:

• new methods of applying loads through data surfaces
• bolt preload modeling
• support for a new dynamic design analysis method (DDAM) for shock spectrum analysis
• increased support for dynamics analysis, in particular complex modes and rotor dynamics
• substructuring using superelements
• new linear contact options
• fluid modeling using the virtual mass fluid modeling
• new composite layup modeling interface that allows easy set up of composite plies with interactive calculation of equivalent laminate properties
• expanded data surface capability to include 1-, 2- and 3-D data surfaces that allow results data transfer to another model for subsequent analysis
• further extensions to the user interface, in particular the Model Info tree
• new capability to expand geometric surfaces to solids, access to API utilities through “Customer Tools” toolbar
• increased post process results control for contouring of partial models.
