Dear all I am trying to interpolates point field to xml field using the FieldConvert module. When I run the command on one older version of Nektar, works without any issue. nektar++-4.3.5/build/utilities/FieldConvert/FieldConvert -m interppointdatatofld FlowCorner.xml FlowCorner.wear.pts FlowCorner.wear.fld Interpolating: 100% [=================================================] Writing: "FlowCorner.wear.fld" But, when I try to run on the master branch I get the next error message nektar++/build/utilities/FieldConvert/FieldConvert-g -m interppointdatatofld FlowCorner.xml FlowCorner.wear.pts FlowCorner.wear.fld Fatal : Level 0 assertion violation Where : /home/mejia/nektar++/utilities/FieldConvert/FieldConvert.cpp[587] Message : Module(s): InputPts should not use xml or fld inputs. terminate called after throwing an instance of 'ErrorUtil::NekError' what(): Level 0 assertion violation Where : /home/mejia/nektar++/utilities/FieldConvert/FieldConvert.cpp[587] Message : Module(s): InputPts should not use xml or fld inputs. Aborted (core dumped) The files that made the interpolation are in a different path on each version nektar++-4.3.5/utilities/FieldConvert/ProcessModules/ProcessInterpPointDataToFld.cpp nektar++/library/FieldUtils/ProcessModules/ProcessInterpPointDataToFld.cpp Does someone have any idea or could help me with some hint? --- Manuel Felipe Mejía De Alba.
