error reading "NMGDepths" while running Hydrodyn

Postby Moti.Keinan » Thu Mar 07, 2019 2:23 pm

Hello Jason,
i am trying to run Hydrodyne independently (not under Fast).
in the section MARINE GROWTH an error message: "invalid numerical input ... trying to read NMGDepth"
the attachment contains copies of the DOS command window and of the related line in the input data file.
thank you, moti

Dear Moti,

My guess is your HydroDyn input file is formatted improperly somewhere in the file. As with any input file format problem, I suggest that you use the Echo option from the input file to debug errors in the input-file processing.

Hi,

echoing didn't help.
an error message in other trials of running HydroDyn was in the section: MEMBER CROSS-SECTION PROPERTIES,
that can't read NPropSets.

thanks, Moti

Dear Moti,

Please attach your HyrdoDyn input file and the associated echo file.

Dear Jason,

The extensions of the 4 attached files are txt because i failed to attach otherwise. i hope it is ok.
The run of "hull" was aborted due to failure reading NMGDepths and "hull2" was aborted by NPropSets.

Bests, Moti

I don't see that the files were attached.

Apologizing for the inconvenient, Moti

Dear Moti,

Looking briefly at your files, I see that:
  • The "hull" file is failing because you've set NFillGroups=0, but you still have a row of data in the subsequent table (beginning with " 32 1 2"...).
  • The "hull2" file is failing because you've set NJoints=2, but you have 3 joints listed in the subsequent table.
I hope that helps.

Hi Jason,

Finally the simulations ran. Your comments also helped me to identify the other bugs.

Thank you very much, Moti
