This article presents an approach that could be used to visualize fluid properties at a y+ value of interest
Details
This article presents an approach that could be used to visualize fluid properties at a y+ value of interest.
Y+ values cannot directly be used to create isosurfaces because y+ values are available only at the boundary. The suggestion here is that we will map the surface data unto the volume and from there compute a “volume y+”.
The following is using an example with a simple pipe flow for which the sim file is attached:

The following is using an example with a simple pipe flow for which the sim file is attached:
- Extract X,Y,Z, and Ustar into a table. Tables > New Table > XYZ Internal
2. Use a tabular data mapper with that table to map Ustar to the volume
3. Compute the “volume y+” using the mapped Ustar with a user defined field function:
4. Create a derived part isosurface for the new field function and set it to the y+ of interest.
5. You can then plot other quantities to visualize using the derived part.
