[Nektar-users] Output of L2 and LInf norms during simulation

Dear Nektar++ community, I would like to know how it's possible to get the L2 and LInf norms during a simulation at every InfoStep and not only at the end of a simulation? Is there an easy way to do so? The postprocessing tool of fieldconvert just can do it at every CheckStep and to do so I will have to do it very often and I always need a chk.-file. Furthermore (maybe it's a bug) the postprocessing module "printfldnorms" of fieldconvert always compares to an exact solution of 0 and never to the given exact solution (but the ouput file of the solver itself compares the exact solution - so there is only a bug in the postprocessing tool). I hope I will get an answer. Thank you. Best regards Fabian Selbach
