Femap 11 Results Data Considerations Quantity of results data generated continues to increase Model sizes continue to increase Advanced analyses with incremental solutions can create huge amounts of data Dynamic response time or frequency steps Nonlinear load or time steps Time to access data increases Database sizes can become very large and unwieldy to manage The solution: Option for external results files that can attach to the Femap modfem database file

Femap 11 NST External Results Example I was very impressed with the performance of the external results capability in Femap v11. Using this new feature, we were able to significantly reduce processing time while keeping the computer resource usage low. Reopening a large analysis result file was over 200 times faster. This is great news for CAE users who are concerned about the trend of increasing analysis model sizes. Cong Yuan, Engineering Department, NST

Femap 11 Graphics Performance Improvements Vertex Buffer Object (VBO) An OpenGL feature that allows data to be uploaded to the graphics card Offer substantial performance gains Vertex data resides in graphics card memory rather than system memory Vertex data can be rendered directly by graphics cardVertex Buffer Objects (VBOs) are Buffer Objects that are used for vertex data. Since the storage for buffer objects is allocated by OpenGL, vertex buffer objects are a mechanism for storing vertex data in "fast" memory (i.e. video RAM or AGP RAM, and in the case of PCI Express, video RAM or RAM), thereby allowing for significant increases in vertex throughput between the application and the GPU.

Femap 11 Working with Legacy FE Models It is sometimes necessary to work with legacy FE models for which there is no underlying geometry available, only the FE mesh Performing model updates to such models or simply changing the mesh density is difficult and time consuming Error prone: danger of not adhering to the original geometry topology The solution: Femaps create geometry from mesh capability
