For rotating propellers use at least 200 timesteps per revolution.-. For standard pseudo-transient resistancecomputations, use ∆t = 0.005 ~ 0.01 L/U. Thechoice of time step will also depend on thecomplexity of the turbulence model. For Reynoldsstress turbulence models it is more appropriateto use ∆t = 0.001 ~ 0.0025 L/U.Lawrence - Earlier this year, the Information and Telecommunication Technology Center (ITTC) changed its name to the Institute for Information Sciences (I2S).
