Odd mapFields issue/question

Hello, I'm trying to use mapFields to map a solution from the center of a domain to an inlet. I've run a RANS case, copied the data to a new folder, moved the points in the mesh (to align the ~center of the mesh with my new inlet boundary), and then ran mapFields to map the results. This works OK, I do not get any errors, and my data has been mapped and the variable files have been altered (U, k, omega, etc...).
However, when I went to check that everything was mapped correctly, I found an odd problem (which I am not sure why it happened, if it is somehow intended or is related to an error I unwittingly made). Looking at the velocity profile from the original plane (where the data is mapped from) and comparing it to the plane it was mapped to, there is a difference. (See attached image of U+ vs y+) Also, the mesh is exactly the same, so there should be no interpolation issues that I can think of. The reason for this difference is apparent when I look at the data itself, the velocity profile data maps correctly for every point except the one closest to the wall! The velocity normal from the wall appears as follows: Code:
Profile pre-MapFields 0.022711 0.052292 0.090609 0.13256 and so on... Profile post-MapFields 0.017012 0.052291 0.090607 0.132557 and so on... Why is this occurring? Am I doing something incorrectly? Is this somehow intended? Thank you! |
