CellBudgetFile byte count off

[aleaf]

While reading the attached file, flopy appears to have the wrong byte count for iface records, resulting in the following error:

---------------------------------------------------------------------------

I tried looking in the MODFLOW manual for documentation about how iface is written to cell budget output but couldn't find anything.

@aleaf, couple quick thoughts. Are you writing compact budget with aux? You need the following in the output control file: COMPACT BUDGET AUX If you do this, then IFACE will be written as a float to the budget file, and flopy should be able to read it.

Does MODPATH work with this file?

@aleaf, seems like we can close this.
