Model visualizationModel visualization managementand control has been extendedin Femap 10.1 with thesupport of multiple group andcombination group display. Themodel information tree in theFemap user interface providesthe basis for interactivecontrol through new checkboxes, which update thegraphics display of the modelinstantly. This way you can easily control the entities that are viewed on the screen, adding orremoving entities and creating combination groups on the fly as required.

Further enhancements to the model information tree add new element display controls with newcheck boxes that interactively switch on element display by shape or type as well as by associationwith materials and properties. The graphics display can be interactively controlled without having tocreate any groups or layers. This can also be combined with the extended group display functionalityto add even more control over entity display.

Besides the model information tree, access to these new display controls, along with all of theexisting visualization controls, has been consolidated into one dialog box – the visibility dialog box –giving a single point of access to all the visualization and display options.

NX Nastran support enhancementsFemap 10.1 brings new functionality that can be used to interactively define combination load sets.These are load sets that combine multiple loading conditions with a possible scale factor setting, andconform to standard Nastran definitions. For existing Nastran analysis files, it is also possible to readin the load case definitions, including all combination load sets into Femap, which means that theydon’t have to be manually rebuilt inside the program.

SummaryFemap® version 10.1 software is the latest release of the robust finite element modeling pre and postprocessor application known for itstight integration with the Nastran solver. Femap with NX™ Nastran software, an extensive and reputable industry standard CAE modelerand solver, is a part of the Siemens PLM Software Velocity Series™ portfolio. Femap v10.1 extends a more than 20-year history ofproductivity and functionality improvements in FEA modeling and postprocessing for engineers. The v10.1 release focuses on modelingvisualization and NX Nastran solver integration to help finite element modeling and analysis setup.

In the Femap analysis manager, support for analysis control and setup has been extended to encompassmore advanced analysis types including dynamics and nonlinear. Also, existing Nastran input files can beread in and all advanced analysis setup definitions will be preserved in Femap.

Femap 10.1 makes the task of job submission easier with the expanded job queuing functionality.Multiple jobs that can come from multiple models within Femap can be submitted to be run. Femap willset each to run in turn on the local machine and provide status feedback. As each one finishes, Femapensures that the results are loaded into the relevant model file ready for postprocessing. Using the jobqueuing functionality, you can submit multiple jobs to be run and leave Femap to manage each one, andthe associated results data accordingly.

Graphics updatesFemap 10.1 also sees some improvements to the graphics database for geometry-intensive models. Solidgeometry facets are removed from the database during a save, so for models with many geometryfacets, you will see a significant reduction in the model file size needed to store the model. However,while this might lead to a slight increase in model load times, save times will also be reduced.

2D tensor plotIn the area of postprocessing, Femap 10.1 introduces anew 2D tensor plot. These plots can be used to displaypositive X and Y scalar values as well as the direction ofpositive shear flow. Typically 2D tensor plots of forces areused in the aerospace industry to display running loadsthrough the structure.

Graphics displayFemap 10.1 adds new graphics to represent body loadssuch as gravity or rotational acceleration if they exist inthe model, so that they are no longer hidden. Graphicalrepresentation of these loads can be by the model axes,or for rotational acceleration loads around the axisof application.

Composite global plyIn any composite structure it is likely that there will be areas of ply drop-off as the composite laminatechanges thickness. In a finite element analysis model of a composite structure, this means that adjacentelements may contain differing numbers of plies, as the composition of the laminate changes throughthe structure. This can make the task of postprocessing composite structures laborious and difficult.

Femap 10.1 introduces support for globalcomposite plies. For a composite structure,continuous plies can be determined acrossdifferent elements and continuous results datadisplayed. This allows results for the same ply tobe viewed across the finite element model,making the task of postprocessing the results datamuch more straightforward.

Femap performs this calculation independently of any global ply solver computation, such as PCOMPGin Nastran. As such, Femap can be used to view global plies for any composite structure, and resultscalculated by any solver.

Loads and constraintsWith existing load and constraint definitions, it is now possible to update and change the position ofthe load or constraint. This makes it much easier to work with existing loads and constraints makingany necessary updates without having to go back and create them from scratch.

Also, Femap 10.1 introduces a new torque load definition for surfaces, allowing a torque load to beapplied directly to geometry.

Some Nastran-specific load and constraint sets have been renamed in Femap to conform to theNastran naming convention.

Femap 10.1 now supports through thickness gradients for plate elemental temperature loads.

For loads that are applied to more than one geometry entity, the user is now given a choice to alloweither the full load definition to be applied to each geometry entity individually, or dispersed over allgeometry entities, with the new total load option.
