They are Dassault Systèmes, Autodesk, PTC, Siemens (UGS),  Mentor Graphics and ANSYS.

Dassault and Siemens have the complete ecosystem: CAD-CAM-CAE-PLM.  Autodesk and PTC reply more on CAD. Mentor Graphics has a limited presence beyond in the electronics industry. ANSYS is an interesting company focusing only CAE.

Compared with the rank of the previous year (2010), all these 6 companies climbed some potions varying from 1 to 4.  This indicates the demands for CAD/CAE/PLM are getting stronger.  The following table illustrates the ranking of these 6 companies in the last three years.

We will analyze these companies, as well as other CAD/CAE/PLM software companies in other articles.… Read the rest “The Big 6 in CAD/CAE/PLM software industry (2011)”

All textbooks teach you how important the post-processing is. For most Generation Y engineers, post-processing (and maybe even the whole CAE) almost equal to visualization as discussed in this post.

Yes, post-processing is important: it gives you the chance to justify your one-month (or one-day, or one-week, or one-year) work; it shows you something you want or something unexpected.

If you are lucky, you can even show how your simulation matches the experimental results. If you don’t have any experimental data (unfortunately, nowadays, this is not uncommon any more), you can still justify your results against common sense.

Of course, “right” or “accurate” results are not the goal of simulation.  The purposes of simulation usually  include:

• to get some data or insights that are impossible, or impractical, or too expensive, from experiments or physical tests (so that the process or system or physics can be better understood; for PhD students, more colorful figures in papers and thesis) ;
• to diagnose the problems encountered of a system (or a component) in real-world operation (so that the possible causes or scapegoats can be identified);
• to predicate the performance of a system
