Problem Statement: There is a truss bridge, the modelling wind is flowing over it at a high velocity. Find out the variations of velocity around the bridge. CFD: Computational Fluid Dynamics (CFD) is the process of mathematically modelling a physical phenomenon involving fluid flow and solving it numerically using the computational process. In a CFD software analysis, the examination of fluid flow in accordance with its physical properties such as velocity, pressure, temperature, density and viscosity is conducted. To virtually generate an accurate solution for a physical phenomenon associated with fluid flow, those properties have to be considered simultaneously. A mathematical model of the physical case and a numerical method are used in a CFD software tool to analyze the fluid flow. For instance, the Navier-Stokes (N-S) equations are specified as the mathematical model of the physical case. This describes changes in all those physical properties for both fluid flow and heat transfer...

Problem Statement: Laminar water flow in a U-bend pipe (square cross-section) CFD: Computational Fluid Dynamics (CFD) is the process of mathematically modelling a physical phenomenon involving fluid flow and solving it numerically using the computational process. In a CFD software analysis, the examination of fluid flow by its physical properties such as velocity, pressure, temperature, density, and viscosity. To generate an accurate solution for a physical phenomenon associated with fluid flow, those properties must be considered simultaneously.  A mathematical model of the physical case and a numerical method are used in a CFD software tool to analyze the fluid flow.

Problem Statement: It is a laminar pipe flow problem, the inlet velocity profile is parabolic and it varies Sinusoidally with respect to the flow time. Finding out the time vs Velocity graph at the inlet. Simulating the problem by using the named expression in fluent solver. The surface parameters s1 and s2 in 3D are available on boundaries (faces). They can be difficult  to use because the relationship between x, y, and z (the spatial coordinates) and s1 and s2 is  nonlinear. Often it is more convenient to use expressions with x, y, and z for specifying distributed  boundary conditions. To see the values of s1 and s2, plot them using a surface plot.  Reading between the lines of your post, I understand that in 3D your channel is a cylinder and your inlet is a disc. If that disc is in the x, y plane and centred at x0,y0,0, you could simply use an expression along the lines of U0*(1-((x/x0)^2+(y/y0)^2)). Alternatively, you could define an additional, cylindrical coord...
