Hi,
Besides the question below, is the filter "point interpolation" is used for more advanced interpolation scheme? Can I use this filter to obtain more accurate interpolation result? Anyone who could explain this filter to me? I just couldn't find any tutorial on this filter. Many thanks, Wilson From: HongchaoWang [mailto:[email protected]] Sent: Friday, 18 August 2017 11:37 AM To: '[email protected]' <[email protected]> Subject: Interpolation error in paraview I'm just wondering what interpolation scheme is used for data manipulation in Paraview? I'm using Paraview 5.2.0. I want to measure the velocity very close to a wall surface so that I can obtain the wall shear stress. However, I found the velocity measured using Paraview is different from the results I have obtained using the postprocessing tool in OpenFoam. Compared with the analytical solution which is already known in my case, Paraview result is worse and is 10% smaller than the analytical solution while the OpenFoam result agrees with the analytical solution very well. With finer mesh, the difference between the Paraview and OpenFoam results becomes smaller, so I believe the difference is due to the interpolation error. Anyone who has experience on this problem? Is there any advanced interpolation scheme that I can use in Paraview? Many thanks, Wilson
