What is FEA (Finite Element Analysis) in CAD?

Fri Nov 22, 2019


Engineers have the unenviable position of being held entirely responsible for the integrity and safety of all the products and structures they design. Small mistakes in design often lead to imminent disasters (that frequently go to court and get litigated). 

This is why products and structures go through an array of stress testing and optimization before being deployed in the real world. But doing so over hundreds of iterations (and to scale) can be prohibitively expensive. So engineers often look to simulation modeling techniques (like Finite Element Analysis) to automate and simplify this testing.

This helps to reduce the use of materials for iterative prototyping, which would otherwise be used in actualization. 

Finite element analysis is one of the most common techniques used by engineers and CAD designers to simulate “stress” on their designs.

Managing Data for Today’s Additive Manufacturing Workflow

Wed Oct 2, 2019

As manufacturers begin to rely more and more on additive manufacturing (AM), moving from a few select piece parts that are 3D printed, to hundreds of assemblies in complex systems, a cohesive methodology is needed to manage this transition and associated workflows. Companies have tried to deal with these complexities and challenges with point and home-grown solutions, trying to adapt legacy systems to the new reality.

VoxelDance Makes Additive Manufacturing Data Do the Samba

Thu Sep 19, 2019

To the uninitiated, 3D printing may seem a simple process — download your CAD file and hit print. But the world of additive manufacturing is more complex. A manufacturer will have to contend with a range of data formats of varying quality (especially if a manufacturer is having to deal with multiple subcontractors for an assembly). This data needs to be correctly translated, made watertight, and made manufacturable — all while retaining design intent. Then a manufacturer needs to combine as many parts as possible to minimize both print time as well as wasted material.

3D Data Translation in 3D Modeling

Mon Jan 14, 2019
The increased use of mobile devices in engineering processes has the interesting side effect of requiring the engineering applications to share data with other systems. An Internet search for open systems and interoperability returns a common quote that, “Interoperability is the glue that holds open systems together.” This interoperability may be simply for visualization, but as usage grows more sophisticated, a much richer data set is required. For example, an engineering mash-up sourcing data from several systems may need to access geometric data accurately while preserving design intent.

STL File Problems: Common Problems Identified in the STL File Healing Process

Thu Feb 22, 2018

When coming from a standard format, very often that data has to be repaired or improved, and Spatial does that as part of our interop product.

Generating Simulation Data from BIM Datasets

Tue Feb 6, 2018

One of the important uses of 3D models in the building information modeling (BIM) process is as inputs to analysis. There are many different areas of building analysis, the most obvious ones being structural analysis for static loads, for dynamic loading under winds, or the stress resulting from earthquakes .

Rounding Dimension Values from 3D InterOp

Wed Aug 16, 2017

 Recently I was asked a question about one of the standard test files generated by NIST (National Institute for Standards and Technology) that was being translated by our 3D InterOp translator.  The question concerned the diameter of a hole in the geometry with a dimension on it specifying ⌀0.238, which sounded innocuous enough at first.

One-Way Associativity for 3D CAD Analysis Applications

Tue Mar 1, 2016

Analysis applications often use solid models generated by CAD systems as their input; for example, the structural analysis of an engineering model. The user of the system applies a set of loads and boundary conditions to the model, and then the software performs its analysis and supplies a set of deformations or stresses in the material, allowing an engineer to look at the results and decide whether the design fits its purpose.

Top 5 Things You Should Know When Considering Data Translation

Tue Apr 2, 2013

1. Don't Reinvent the Wheel
You're designing a new product, but you have an old part that's almost right for the job. Don't redesign it from scratch, import it from its source format and tweak it to meet your current needs.

2. Keep it Tight
If you're designing a part for manufacturing, you need the end product to be water-tight. If your model is “leaky”, your production run might just sink before it gets ever gets launched. If you’re re-using data files and they are not in the best of shape, importing them may help to patch some of those holes during the healing phase and make for clear sailing during production. In this way, data re-use not only extends the life of the model, but it may very well make your model ship-shape to boot!
