Review Article
  • CFD: Don't be Scared March 06, 2010
    Reviewed by 'John Chawner'
    Thanks for giving mesh generation top billing (or at least equal billing) with CFD in the recent article "CFD: Of Meshes and Math". Products like Mentor Graphics' FloEFD and Blue Ridge Numerics' CFDesign (among others) are helping make CFD more accessible to design engineers (aka non-expert analysts).
    But I have to take minor issue with the tone. This whole "fluid dynamics is hard" business reminds me of Barbie's "math is hard" but without the corresponding outrage. Yes, engineering *is* hard. That's why we go to school for 4 (or many more) years to become adept at it. Yes, CFD is hard but so is FEA (which also requires a mesh) but no one thinks twice about pounding out a bunch of FEA simulations. Yes, some engineers don't fully get CFD and then others of us (like me) get the "deer in the headlights" look when presented with a structural fatigue problem.
    Stepping down from the soapbox, I agree with your assessment that CFD will continue to grow as the overall use of computational simulation increases. After all, simulation during the early stages of design leads to all sorts of good things including better products and quicker to market. And, mesh generation will be a driving factor in making use of CFD more efficient and effective. After all, your simulation is only as good as your grid.
    Thanks again for some superb insights.
    Full disclosure: At Pointwise we deliver mesh generation software and services to CFD practitioners worldwide.

    Dear Jeff:
    Thanks for your MCAD Weekly piece on "CFD: Of Meshes and Math". You caught the mood perfectly of many of us mechanical engineering students in our undergraduate years in fluid mechanics classes.
    You're article was an excellent follow-up to the November 09, 2009 EDA Weekly posting of "MAD Progress":
    Keep up the good work!
