Fluent Induced Drag Aerofoil Convergence Error
I am currently modelling what happens, to lift induced drag, when you apply washout to a wing (Twist). However I have a few issues the drag values I calculate are into the 1000s the drag values ...
What EXACTLY are the "outflow" and "pressure outlet" BCs in ANSYS Fluent?
I am just starting my MSc and we have been given an assignment in which we must model two-dimensional, laminar, incompressible Poiseuille flow in a channel. We are supposed to use a VELOCITY INLET ...
Aerofoil study using CFD, struggling to find aerofoil coordinates
I’ve been messing around with Ansys and I’m struggling to find the aerofoil coordinates for a NACA 66-012? I looked on Airfoil tools, but it doesn’t allow you to generate a 6 series aerofoil, only 4 ...
Initializing Fluent using CGNS
I am trying to import data generated external to Fluent using CGNS (CFD General Notation System) files. The data consists of velocity vectors, temperature, pressure, density, and species mass ...
What is temporal order of accuracy of the PISO algorithm?
A few Computational Fluid Dynamics (CFD) codes implement the so called PISO (Pressure-Implicit with Splitting of Operators) algorithm for pressure-velocity coupling. My concern is what is actual ...
Implementing pressure inlet boundary condition
I am interested in implementing pressure inlet boundary conditions for the 2D compressible Euler equations. My equation of state is an ideal gas ($p=\rho R T$) which is thermally prefect but not ...
ANSYS Fluent: Defining External Force on a Cell Zone [closed]
I am using ANSYS Fluent 15 to simulate a case of fluid flow. In my case, I have three cell zones in my simulation, let's call them top, middle and bottom. My requirement is to put a vertical constant ...
Hypersonic flow in Fluent
I am working in my graduating project about the hypersonic flow, particularly the properties of the air behind a strong shock wave, I try to do a simulation for that process in Fluent but I don't know ...
CFD: Mesh problem [closed]
I wish to study the 2D heat transfer of the soda can using Fluent. For my geometry I took a circle. My problem while meshing the circle; Because i need to mesh it from inside. I used the mapped faced ...
