As a new element of Simulate to Innovate, we will be offering guest posts written by thought leaders from within our partner companies of the Altair Partner Alliance. As a first edition, we have a post from J. Marczyk, founder and CTO of Ontonix, who discusses the limitations of refinement when creating FE mesh in design concepts: 

As compute power increases, it has become easier to generate FE meshes quickly and efficiently. This allows analysts to reduce the discretisation error. However, many people overlook the fact that models are already full of sometimes quite drastic simplifications of physical phenomena. For example, the equation of the Euler-Bernoulli beam – the simplest of structural elements , is the result of at least the following assumptions:

  • The material is homogeneous.
  • The beam is slender.
  • The constraints are perfect
  • The material is linear and elastic.
  • The effects of shear are neglected.
  • Rotational inertia effects are neglected.
  • The displacements are small.
  • Sections remain plane. Read More

Additive Layer Manufacturing (ALM) has been around for some time.  I got involved with this industry almost 20 years ago when it was called Rapid Prototyping and then 3D Printing and now ALM.  ALM builds structures layer by layer which is different than traditional manufacturing methods which either starts with a shape and machines away the excess or uses tooling to form a part to net shape. Some ALM processes rely on lasers to cure or solidify the material and others deposit the material through tiny nozzles but all methods build up a part in thin layers.

It has been a great technology for creating prototypes but has had little application in making production parts.  New methods and new materials have emerged more recently that may be able to make ALM more relevant to production applications. A good article appeared recently in Technology Review that discusses some of the current and future applications of the technology.   Altair recently had an ALM panel at our European Altair Technology Conference where leaders from the industry discussed the technology and its applications.

The 3D Printing Wave

, Executive Director - Global Aerospace

There has been a lot of buzz around 3D printing lately.  Actually, I got involved in this industry in the early days when it was called rapid prototyping and stereolithography was the only technique.  It is great to see the development of this industry and the wide variety of materials now available.

Altair’s OptiStruct technology and 3D printing are becoming great partners.  OptiStruct’s topology optimization creates the most efficient structure for the given loads as recently described in a Forbes article.  It produces organic-like structures that can sometimes be difficult to manufacture.  3D Printing gives us the opportunity to directly print any structure we can imagine so we can now truly manufacture the most optimal design.

At our recent Altair Technology Conference in Turin, Italy, we brought together industry leaders and experts in the use of 3D printing technology to discuss this technology and where it is going.  It was a great session and shows how 3D printing and topology optimization can revolutionize the way we design and build in the future.  You can read more about this session and review the presentations here





Recently, the team and I spoke with Digital Manufacturing Report to discuss the ways manufacturers’ growing reliance on CAE is challenging the industry to continue to evolve its software offerings. Driving factors like innovations in HPC and cloud technology are paving the way for technology advancements that enable manufacturers to solve more complex problems and deliver better usability across the enterprise. We discussed how the recent release of HyperWorks 12.0 addresses this evolution in “Altair Takes HyperWorks to the Cloud.”

Here’s an excerpt: Read More

As noted in the 2012: Simulation’s Year of Discovery post that I wrote last December, the impact of simulation continues to reveal itself, enhancing everyday products and our daily lives. From innovations in speed and crash modeling to light-weighting vehicle, aircraft and consumer packaging designs, industries are continuing to discover new ways to use simulation technology as we move through a new year. But what does that mean for simulation in 2013? How is the definition of “everyday” being shaped by technology? Read More
