Specifically, I used the following command: FieldConvert input.fld output.fld However, it seems to me that the default conversion cannot take different options of points styles into account. When a xml file is included in the command： FieldConvert example.xml input.fld output.fld Although the output.fld file appears to have the correct SHAPE and BASIS settings, the resulting field data still differs significantly from the original Nek5000 solution. On the other hand, even though I manually ensured that the polynomial order settings are consistent between the two formats and that the POINTSTYPE is set to GaussLobattoLegendre, the resulting output.fld file does not appear to fully or accurately reflect the original Nek5000 field data. Some components seem to be missing or incorrectly mapped. I would appreciate any guidance or suggestions you might have on ensuring a more complete and accurate conversion. Are there any known limitations, specific configuration requirements, or pre-processing steps for converting Nek5000 fields to Nektar++ format? Thank you very much for your time and support. Many thanks, Xingyi Wang Harbin Institute of Technology
