MODFLOW 6 PRT model cannot read GWF binary output files created by MODFLOW 6 GWF

[gschampion]

I ran a steady-state MF6 GWF model (DISV grid) with SAVE_FLOWS, SAVE_SPECIFIC_DISCHARGE, and SAVE_SATURATION options in the NPF Package. I used list_records() from flopy.utils.binaryfile to check the binary budget file. The first three records are FLOW-JA-FACE, DATA-SPDIS, and DATA-SAT. These are followed by records for all of the stress package and mover instances.

Can anyone infer what might be wrong with the binary budget file, or what I am doing wrong?

I then used the binary budget and heads files as input to a simulation using only the particle tracking model PRT (i.e., in the FMI Package). Despite the budget file containing records for all of the flow components, MF6 gives the following error report:

UNKNOWN PRTFMI PACKAGEDATA: PRTBUDGET
UNKNOWN PRTFMI PACKAGEDATA: PRTHEAD

SPECIFIC DISCHARGE NOT FOUND IN BUDGET FILE. SAVE_SPECIFIC_DISCHARGE

AND SAVE_FLOWS MUST BE ACTIVATED IN THE NPF PACKAGE.

SATURATION NOT FOUND IN BUDGET FILE. SAVE_SATURATION AND SAVE_FLOWS

MUST BE ACTIVATED IN THE NPF PACKAGE.

FLOWJA NOT FOUND IN BUDGET FILE. SAVE_FLOWS MUST BE ACTIVATED IN THE

NPF PACKAGE.

UNIT ERROR REPORT:

Error occurred while reading file
