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 2018-03-27 15:55 GMT-03:00 Manuel F.

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?
