Femap is an advanced engineering simulation software program that creates finite element analysis models of complex engineering products and systems, and displays solution results. Femap can virtually model components, assemblies or systems and determine the behavioral response for a given operating environment.
Using Femap’s digital simulation capabilities you can:
- Predict and improve product performance and reliability
- Reduce time-consuming and costly physical prototyping and testing
- Evaluate different designs and materials
- Optimize your designs and reduce material usage
Analysis Studies can be used to help organize output into more orderly and understandable data sets. You can group output sets from different analysis types into separate analysis studies and operate on them collectively. You can also envelope analysis studies to collect output maxima and minima across collections of output sets.
Free Body Section Cut
In Femap 11.2, you can gain a faster understanding of load paths through the model with a free body section cut, which you can interactively move through the model along a predetermined path. The section cut is defined using a cutting plane where the free body summation is calculated and displayed for all the contributing nodes and elements.
Femap 11.2 introduces new geometry modification tools that allow you to edit geometry entities interactively, including closing modeling gaps that typically occur following a mid-plane extraction command. You can interactively correct or repair problematic or incorrectly defined geometry as well. The Geometry Solid Slice commands available in previous versions of Femap have been consolidated to provide simpler execution and expanded functionality, and you can now slice solids using surface or curve geometry as cutting tools
A new Contact Manager Data Surface functionfacilitates the setup of contact between components in a solid model. Show, hide and highlight options give you improved visibility of contact surfaces in the model, and you have direct access to the contact property definitions. Enhancements to element/property relations include more efficient definitions of tapered plate structures using shell elements, and spring/damper coordinate system definitions.
You can increase the accuracy of solid tetrahedral models with the new ability to control of the number of though-thickness elements when meshing the models. Similarly, you can now define the number of splits for the Edge Split command to split an element into multiple elements. Edits to rigid elements are now easier with improvements to rigid element connectivity definition. You can now check the model according to the NX Nastran element quality checking definitions to ensure that the model will not fail due to poor element quality before submitting for analysis.
Femap with NX Nastran
The range of capabilities in the base module includes linear and statics, normal modes, buckling, basic nonlinear and heat transfer. In addition NX Nastran for Femap includes additional options for dynamics – that includes transient/dynamic, frequency/harmonic response, response spectrum, random response DDAM (Dynamic Design Analysis Method) – as well as advanced nonlinear analysis, aeroelasticity, superelements, optimization, rotor dynamics and DMAP (Direct Matrix Abstraction Program).
