Vortex Visualization – Q-Criterion
Large values of Q correspond to regions of high angular velocity close to the vortex cores.
Courant Number, CFL and CFL Condition
Even though the differences are very subtle, they exist and I propose an explanation here that can help new researchers in this field.
Structured mesh vs. Structured calculation
A structured mesh will not necessarily be calculated as such.
Turbulence: more deterministic than you think!
Turbulence is a deterministic (non-random) phenomenon, being treated as random only for modeling purposes.
