Hi,
I'm trying to convert a field to some specific points.
I tried to use:

mpirun -np 32 FieldConvert-rg -m interppoints:fromxml=1cylQ3D_msh2.xml:fromfld=1cylQ3D_msh2.fld:box=400,200,300,-1.0,3.0,-1.0,1.0,0.001,3.0 1cylQ3D_msh2_2059.dat

and i get a "Segmentation fault" as result.
Then I tried as a simple test:

 FieldConvert -m interppoints:fromxml=1cylQ3D_msh2.xml:fromfld=1cylQ3D_msh2.fld:topts=file.csv file2.dat

The file.csv:
# x, y, z
5.0,-2.0,1.0
7.5,2.0,1.0
8.0,5.0,1.0

And had the same "Segmentation fault" as result.
Before all of that, i was converting my fields to paraview and then converting to csv files.
I'm spanding to much time. There is a method to generate a csv field direct from nektar?

Thank you for your support.
Alessandro
