Hi Manuel,

The latest master includes some small changes to the usage of the interpolation modules.
The pts file is now passed using the "frompts" option, so the correct command is
    FieldConvert -m interppointdatatofld:frompts=FlowCorner.wear.pts FlowCorner.xml FlowCorner.wear.fld

Cheers,
Douglas

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.

Where   : /home/mejia/nektar++/utilities/FieldConvert/FieldConvert.cpp[587]
Message : Module(s): InputPts should not use xml or fld inputs.

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?
