CFD in 2014

cfd in 2014

When a reader asked me whether there would be a post for CFD in 2014, I realized it is time to think about 2014.  CFD in 2013 is entering its grave. This post is the final nail in the coffin for that old post. So, it's time to talk about CFD  in 2014. Of course, I don't ...

Why isn’t open source CFD solution for everyone?

gnu-head

When open source CFD solution is talked, two familiar statements are often heard:  Open source CFD solution is cheap because nothing can be cheaper than free.  Open source CFD solution is inferior, otherwise, why is it free? Both of them are wrong. Open source CFD solution is not cheap, although licensing is free Most open source CFD packages ...

CFD in 2013: what will change? what will not

Mayan-Apocalypse

Obviously, the doomsday didn't come. It proves again it is hard to predicate what will happen when you don't have sufficient knowledge of how the system works now. Maybe it is just a bug in Mayan's calendar (Google also forgot to put December in People App in Android 4.2 (aka Jelly Bean 4.2)  last November). Predicting ...

From post-processing and visualization to simulation result exploration

moon-exploration

We all know post-processing because it is part of CAE. 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) ...

The best 3 answers to “Why is visulization important for CFD?”

cfd-guerrilla

Last year, FieldView jumped into Altair's bed, and now got a baby named AcuFieldView in the latest AcuSolve package. Recently, FLOW 3D was married happily with EnSight (CEI), and will get EnSight 10 integrated into FLOW 3D in a few months (this fall). It seems most CFD software vendors now are aware of the importance of post-processing capabilities. ...

Top 5 misunderstandings on (good) mesh

meshing-world-map-tri

Although there are quite a few mesh-free (mesh-less) FEA and CFD codes, meshing is still one of the most important tasks for most CAE users. The importance of generating high-quality mesh can never be overemphasized. But how to define a high-quality, or more preciously good, mesh? Reading the output of mesh quality report in your meshing ...

Partnership in CAE Industry

partnership-in-cae-industry

Like in any other industries, the partnership is not new among CAE players, big or small. A technical partnership usually creates a win-win situation; at least, this is the major intention of forming the partnership. The two parties involved usually are not balanced: a big shark in the CAE or PLM market and an almost unheard ...

CAE in the Cloud, Is It Just Hot Air?

is-cae-in-cloud-just-hot-air

Cloud computing now is one of the fastest growing sectors in the IT industry. How will this affect the CAE industry? Actually, cloud computing is not new for CAE industry, especially for CFD users. 15 or 20 years ago, when you accessed supercomputers in the computing centre from home or office through dial-up modems (do you ...

Navier-Stokes vs lattice Boltzmann: will it change the landscape of CFD?

navier-stokes-boltzmann_350-350

For most people,  CFD is about continuity and Navier-Stokes equations.  But this is not always true. One of the alternatives for CFD simulation is the lattice Boltzmann equation (LBE), where the fluid is treated as fictitious mesoscopic particles (not molecules). If you need something to make you sleepy, please read the short (and concise, and free) ...

CAEWatch, WTF?

dog-queue-for-pee

CAE Watch is the information hub for CAE professionals. From respected industry experts of finite element analysis (FEA), computational fluid dynamics (CFD), product lifecycle  management (PLM), we will bring you the in-depth analysis on the computer aided engineering (CAE) industry. We are frustrated with the numerous CAD/CAM/CAE/PLM/PDM magazines, which have articles similar to marketing materials: lack ...
