It seems most CFD software vendors now are aware of the importance of post-processing capabilities. Competition for buyers will be extended from brains to eyeballs. If your CFD software can only draw black and white lines, or can only generate mediocre animations, it seems it will prepare to die, soon.

The trend of getting better visualization and post-processing tools is surely driven by the demands from the customer, although “A lot of times, people don’t know what they want until you show it to them.”

So, if you ask so many called CFDers (CFD engineers, CFD specialist, CFD analysts,  CAE engineers…) why they think visualization is so important. You probably will get all sorts of answers. But probably, the top 3 answers would be:

#1. “My boss can only read colourful things.”

The sad truth is that most of the times the supervisors of the CFDers don’t know CFD (why should they know?). Images … Read the rest “The best 3 answers to “Why is visulization important for CFD?””

Predicting the future of CFD is similar to weather forecasting, maybe just like Mayan’s Apocalypse.

But this does not stop us from expecting a new prediction, just like you check the weather forecast before travel.

As my first degree is meteorology related, please do not expect the prediction is more accurate than weather forecasting for the next 365 days.

#1. Automated meshing:  a classical fairy tale continues

Fairy tales always have listeners, and of course, tellers as well. When you are young, you are listeners; when you are older, you may gradually become a teller.  What has not been changed is the story.

Automated meshing is such a classic fairy tale in CFD industry.

Meshing is always one of the most challenging tasks for most real-world CFD problems (I am not talking about flow over an infinite plate). Automated mesh generation is the dream … Read the rest “CFD in 2013: what will change? what will not”
