points file created by "surfacesSampling" is in disorder

Hello,

I used the surfaceSampling utility to creat the velocity surface data for timeVaringMappedFixedValue boundary condition. I chose a faceCentres file in one of time-series surfaceSamping folders, then renamed it as "points" for the input.

I confirmed that I have the same point number in my points file and my velocity surface data file.

But it is strange that they are numbered differently. Normally, my inlet should be:

But, now it looks like:

I have this problem when I used a HPC cluster with 18 processors. I double checked it in my own PC with 18 processors. The two files match. I cannot understand.

I attach the points file and the velocity file. Hope you can give a help.

points.txt U.txt

Best Regards,
