Default Appropriate bocos for POPINDA output

Hi guys,

I could really use some help! As I have found absolutely nothing about output for popinda solvers yet, I must be one of the only few using this functionality, but as making this work would save me a lot of time further in my process, here goes:

I have (succesfully) created a 2D structured HEXA mesh for a jet engine in a farfield. Now, for an acoustic solver (PIANO) I require a .popform data file, which ICEM CFD can produce directly by the POPINDA solver functionality under output. I seem completely unable, though, to get a proper .log file for the boundary conditions. All conditions in this output file are specified as 'unspecified BCs', as can be seen in the screenshots.

The steps I have undertaken:
  • Import geometry
  • Divide geometry over different parts (ENGINE_CORE etc..)
  • Do the blocking
  • Yes I am very sure that all edges which represent the contours (farfield and engine geometry curves) are associated The points are associated to a seperate part called V1, but this shouldn't make a difference (right?)
  • Create structured multiblock mesh
  • Set BCs under Output (for POPINDA)
  • Set par file under Output
  • Export .popform and .log input files
I've read somewhere else that it can be important to first define the BCs and then convert the premesh to a structured multiblock, but this does not seem to make any difference in my case.

I've added a ss of the BC and PAR dialog screens, and a part of the .log file (to demonstrate the lack of variation, block 1 should have 3 different bocos..). For clearity, PIANO requires ITYP to be '-1' to indicate an interior edge, '12' for a wall and '21' for radiation (farfield).

Any help is most welcome!
Thanks in advance,
