Tech Tip – Dynamic Analysis

Alan — Fri, 22 Aug 2014 03:00:25 +0000

Femap with NX Nastran allows some “cheats” to run certain types of dynamic analysis, even without the (as usual, very cost-effective) Dynamics add-on. Firstly, given that Non-linear transient simulation is part of the standard capability, this allows a time history analysis to be run – and with the included multi-core / multi-cpu SMP capability.

Femap Tip: Things its not obvious that Femap does

Alan — Sun, 20 Jul 2014 21:43:05 +0000

NX Nastran has a few “secret” capabilities that are not obvious from within Femap. It may not be clear there are two distinct sets of documentation: one set for Femap itself, plus a complete set for NX Nastran. The latter is reached via Help | NX Nastran (from within Femap) and it makes for some

Femap Tip: Solid Meshing with Internal Beams

Alan — Wed, 18 Jun 2014 23:00:04 +0000

Structures like reinforced concrete where steel rebar in encased in solid concrete can be represented by 1-D rod or beam elements for the rebar inside solid 3-D tet-elements for the concrete. When setting up such a model you have to take care to ensure that the mesh is contiguous and that the 1-D elements connect

Delivering a roving science laboratory from Earth to the planet Mars requires meticulous planning and precision performance. You only have one chance to get it right; there’s no margin for error. Engineers and scientists at NASA’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology had to make crucial decisions thousands of times over

Femap with NX Nastran’s Best Kept Secret

Alan — Thu, 22 May 2014 01:55:51 +0000

It is a little known fact that Solid Edge and Femap can be coupled together to provide a complete modelling/FEA solution where the analysis model is connected to the design model in the CAD system. Solid Edge is a comprehensive 2D/3D CAD system for designing parts and assemblies. Its strength is shown when model changes

Femap with NX Nastran TechTip: Groups and Layers

Alan — Wed, 21 May 2014 23:45:57 +0000

Layers and Groups are ways in which complex models can be separated into convenient bits. After years of experience, our recommendations are these: Layers are better for pre-planned separation of significant parts of the model. Remember, entities belong to only one layer. New entities are placed on the Active layer. Copied entities are placed on

Femap and Solid Edge Simulation

Alan — Thu, 06 Mar 2014 06:35:46 +0000

One of the questions many design/engineering organisations face is whether to invest in CAD-embedded FEA or go for standalone general purpose FEA like Femap with NX Nastran. Each has its merits, and in this post we outline why either or both would be the right choice. Why Solid Edge Simulation? The major advantage of Solid
