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 ...

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 ...

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) ...
