Universal File import to NX using API


Dear NX users,


TMG exports universal file and I would like to import node_temperature.unv file into NX  throught the API.   I've used with  FEMAP to do this tas and unfortunately,  there is  no import functionality for I-DEAS .unv files through the API.


Is there any way to import unv. file into NX throught the API for NX post-processing???

Please let me know if it's feasible in NX10


Many thanks,

Results data is never "imported" into NX.


Post Processing works directly with the data in the solver results file. Use NXOpen.CAE.ResultManager.CreateImportedResult() to create an instance of NXOpen.CAE.ImportedResult for the .unv file.

Hello Cats099,


I also use a lot of universal files. Please find below some example code where I specify a .unv file as a result.

I've also added some background in the attached file "README_.txt".


note: keep in mind that there are 2 ways to display .unv results in NX: 1) specify results file 2)add companion results. Both have pro's and cons.

A couple of suggestions:


  1. To be more robust, all .FindObject() calls should be replaced with more reliable selection methods. I.e. if there is no solution named "Solution 1", this journal will fail.
  2. Use methods in System.IO.Path to separate a file specification in to filename, pathname, extension, etc.

Hello Jim,


Thank you for your suggestions.

I will implement these.

Dear Frederik


Thanks for your suggestions. I will try it.
