Hello, forum.

I have the vtk file, wich is several vtk files merged together via AppendDatasets, with cell data type. I apply ‘cell data to point data’ filter to it, then save it as csv file. But when I create plots, based on that csv file, in matlab, I can see that some points have excactly matching XYZ coordinates but different values of flow parameters (see picture).

I try to combat with that by changing of precision when I write csv file, but it has near no effect.

Does anyone face such problem?
