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 ...

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) ...
