When should I use "intermittency transition" (gamma transport equation) in ANSYS?

I've worked on simulating 3D VIV (a cylinder forced by Karman vortex street) and been stuck with settings. Considering the transition to turbulence due to the oscillation of cylinder (Re≤200,...

Recommended CFL number while using Coupled scheme to simulate 3D VIV with ANSYS?

G'day, I want to use Coupled scheme to calculate this case and therefore need to setup a suitable CFL number (Courant number). The CFL number in this scheme isn't used to calculate adptive time...

Any recommended scheme for 3D VIV simulations with ANSYS FLUENT?

G'day, I've tried several different settings to find a optimal scheme for 3D VIV simulations. Basicly, I'll keep using PISO since it's highly recommended for transient flow. (and with Green-Gauss...

Centroid of the geometry always has deviation in ANSYS Mechanical, how to solve it?

G'day, I'm a beginner to ANSYS, and I met a strange problem. The centroid of my cylinder, which should be at (0,0,-150), can't be the same position in Mechanical (as pic shown). I imported the...
