help with input error? #78
Comments

Hi Howard,
This is an input conversion error indicating that the file is being read but the code cannot decipher what is being read. For example, the code is reading a text string when expecting a real number. Can you look at the MT3D output file and see what was read last from the SSM file and it may possibly also point out the line on which the error occurred. That may help you debug the SSM file and point out what is causing the error.

I'm running into problems adding MT3D-USGS to an existing MODFLOW model. Its a pretty large model, so I am using flopy to add MT3D-usgs.
I am getting an error on the SSM package:
forrtl: severe (64): input conversion error, unit 4, file FWP_sire_mt3d.ssm
Can you point me in a direction to look to track down the error? Thanks

@hwreeves-USGS Also, since you're using flopy to generate the MT3D-USGS input, there may be an issue with what flopy is dumping to the SSM input file. If you're able to share your model, I can try to take a look and see what's going on from the source code if @vivekbedekar suggestion doesn't turn up any clues. |

thanks Eric, I think it was missing lines related to the UZF package (7-10 of the input instructions) -
but now I think I have an issue with the LMT8 package and the 'PACKAGE ALL' option. I have
some other things to work on this morning but hope to have time this afternoon to look
into the problem a bit more.

@hwreeves-USGS in case it is helpful, here is an example of the LMT input. Note that you want to use |

Thanks Eric,
I had
PACKAGE_FLOWS ALL
and tried
PACKAGE_FLOWS SFR UZF
But now I am getting a Program Exception- stack overflow error
The end of the list file has:
SAVING SATURATED THICKNESS AND FLOW TERMS ON UNIT 54 FOR MT3DMS
BY THE LINK-MT3DMS PACKAGE V7 AT TIME STEP 1, STRESS PERIOD 1
The model is pretty large, I have the icbnd set to a smaller region in
MT3D-USGS; but that isn't used here I guess. Do you think this
is related to the model size?
I'm running MODFLOW-NWT_64

OUTPUT_FILE_NAME gwt.ftl
OUTPUT_FILE_UNIT 20
OUTPUT_FILE_HEADER Extended
OUTPUT_FILE_FORMAT FORMATTED

Hello @hwreeves-USGS, I assume you're using the most recent release of MF-NWT? Earlier versions might have issues. |

I think I am using the latest, but will get new version and try that just in case.
