I have been struggling to get the same parabolic velocity **profile** (as provided in the udf) in the **fluent** solution for a straight smooth laminar pipe. I changed the geometry many times. For example, (i) inlet face center was at the origin of the coordinate system, (ii) inlet bottom edge was at the origin of the coordinate system, etc. Hi, I'm making laminar fluid flow devices and want to. Polynomial **interpolation**: This is the most generic **interpolation method**, as it involves fitting a polynomial to a set of grid points to generate a mesh. Technically, polynomials of any order can be used for mesh **interpolation**, including linear **interpolation** used in simple meshes or higher order polynomials with highly accurate results. In this **Fluent** Tips & Tricks video, we show how different initial values (initialization) can be applied to different areas of a mesh. The standard initiali. **Interpolation Method**. **Interpolation method** determines the connection mode between each two control points. You can select “B Spline” or “Linear” Control Points. Vertical **profile** design is achieved by controlling the relative position of multiple points. You can use a small number of points to achieve quick shaping, or you can use more points to describe in more detail. You are.

Many **interpolation methods** exist. Some are quite flexible and can accommodate different aspects of the sample data. Others are more restrictive and require that the data meet specific conditions. Kriging **methods**, for example, are quite flexible, but within the kriging family there are varying degrees of conditions that must be met for the output to be valid. Geostatistical Analyst. Profiles written using the Write Profile dialog box and profiles of experimental data in random order are examples of point profiles. ANSYS FLUENT will interpolate the point cloud to obtain values at the boundary faces. The default interpolation method for the unstructured point data is zeroth order. In other words, for each cell face at the boundary, the solver uses the value from. **Profiles** are for surfaces. For source terms you'll need to read & assign the data into the source term so you'll need the file read functions and (possibly) some **interpolation** routines to add in values assuming the mesh & points don't line up. mikeneu Posts: 10 Member October 2021 Dear Rob, Thanks for your reply. **FLUENT** V6 - Reading experimental/tabulated values of material properties or **profiles**. **FLUENT** provides for a variety of **methods** for specifying material properties, including polynomial functions, piece-wise linear functions, etc. User-defined functions can also be used to specify material properties and variable **profiles**.
