  1. Hi Adam:

    Sorry for the delay in response- your reply slipped past my notice.

    If you look at some of the other MODFLOW output files in the Example1 folder, you'll notice a file called Example1.bc6. This file has the Unit Identifier. It's usually specified in one of the input files that is the flow 'package', which usually contains an 'F' as one of the last letters- in this case BCF6 (all of the packages and corresponding output files are listed in Example1.nam).

    The other thing to note in the .nam file is the unit number for the budget file ... in Example1.nam the unit number is 50. I *think* this can be any number really -- it's just an identifier for the DATA(BINARY) package. That identifier - 50 - is what then needs to be put into the flow package file, Example1.bc6.

    If you look in the Example1.bc6 file you will see some numbers followed by the variable names the numbers correspond to. Since this is a BCF package one of the variables is named IBCFCB. Now what you need to do is set that variable's value to the identifier used for the budget file -- in this case 50. This basically tells the flow package to put its output in the budget file.

    I hope that helps,

    Tom

    Hi Tom,

    the importing from GMS to X2t is finally working. Thank you very much for your help :rolleyes: ! The problem did not consist only in unit identifier. Next problem was caused by formulation of model cell extend along y and z axis in a model output file with suffix .dis (marked by red color):

    # MF2K DISCRETIZATION FILE

    # NLAY NROW NCOL NPER TIMEUNITS LENUNITS

  2. Hi Tom,

    I have looked at the Appendix B.2, still I’m not sure, where I have to change unit identifier (– in Modflow’s output budget file?). I have open example script for import from Modflow to X2t called Example 1. I have looked in Example’s files, but I haven’t seen e.g. IBCFCB unit identifier there.

    My problem consists also in the following guideline:

    The budget file needs to contain data describing flow among the nodal blocks.

    Specify the unit identifier for the budget file as the value for the IxxxCB variable,

    where “xxx” is the flow package in use. The variable, for example, might be

    IBCFCB, ILPFCB, and so on.

    Can you give me advice?

    Best regards,

    Adam


  3. Hallo,

    has anyone ever imported flow field from Modflow to X2t?

    I have a one-layer groundwater flow model in GMS 5.1 (Modflow 2000) and I‘m not able to import output files from GMS to X2t.

    I acted in accordance with the Reactive Transport Modeling Guide. The problem is, that I don’t understand what does it mean - specify the unit identifier for the budget file :unsure: . Where and how have I to set the unit identifier?

    Do you have any experience with this problem ?

    Adam
