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
