d(p)/d(x)=f(x) Now I need a boundary condition for p to get the right wall values. So far, my implementation uses the BC zeroGradient. This will lead to a boundary value that is exactly the cell value. But this is not the solution of the differential equation above. ...
Sometimes it might happen that you can read a mesh file in FLUENT5 without any error and while reading the same in FLUENT6.0 you get following error : Error: access: unbound variable Error Object: p…
Hence, I am puzzled with physical meaning of it and how to apply a boundary condition which would be equivalent to Dirichlet BC of unity on the wall. In fluent I remember, we simply put the constant value of UDS equal to 1. What would be the setting to get similar results in CFX?
In this study the fluent computational fluid dynamics code has been used to evaluate the flow in the port-cylinder system of a DI diesel engine in a steady flow rig. The computational grid is generated directly from 3-D CAD data and in cylinder flow simulations, with inflow boundary ...
Commercial CFD codes such as ANSYS CFX, ANSYS FLUENT, and STAR-CD often incorporate impressive visualization tools within their user-friendly GUIs to allow users to graphically view the results of a CFD calculation at the end of a computational simulation. There also exist, however, many excellent...

The given governing equations have been solved using the commercial CFD software, Fluent 6.3.26, for an automotive rubber part. The software uses a control-volume-based technique to convert the governing equations to algebraic equations that can be solved numerically [11]. The Semi-Implicit Method...
The commercial CFD software Fluent 6.3 is used to solve the N鈥揝 equations. The SIMPLEC algorithm is used to couple pressure and velocity. Second order upwind discretizations have been used for convection terms and the central difference schemes are used for diffusion terms. Three-dimensional ...
I d like to set the characteristic of the pump as an inlet boundary condition of a pipe system. The characteristic of the pump is known Q=f(dp) - mass flow is a function of pressure gradient. Pressure gradient is evaluated during the computation between inlet and outlet of the pipe syste...
