I will look at the inp file and see if how I read the csv file (recall that I replace the commas with blanks) in fortran could be a problem.

I forgot to mention that I am running on my linux workstation the 64-bit binary versions of PV 4.1.0 and 4.3.1 that I downloaded from paraview web site. Are you using the binary or an installation from source on your workstation?.

It is strange that  for a single cylinder I get the correct number of values for the upper and lower parts of the cylinder.

The problem occurs when there two cylinders. I will look at the excel files and if it is correct, maybe I can save it in text format that I can read into gnuplot.
I have no experience with excel nor reading csv in gnuplot scripts.
Will keep you posted.
