I am a new user of Nektar++ and in a bind. Specifically, I am stuck on using the FieldConvert utility to re-construct the decomposed solution files generated when the AcousticSolver was run with mpirun.I have referred to the user guide Section 5.7(Version 5.3.0) but it doesn't work. I tried to run the FieldConvert with 10 processors like this: mpirun -np 10 FieldConvert case.xml case_0.chk case_0.vtu. This didn't work and throws errors. This syntax matches with what is mentioned in Section 5.7 of the user guide. What would be the right way to using FieldConvert when you have solution files that have been generated in parallel run ?
