### PRT-FMI

#### Structure of Blocks

_FOR EACH SIMULATION_

```
    BEGIN OPTIONS
      [SAVE_FLOWS]
    END OPTIONS
```
```
    BEGIN PACKAGEDATA
      <flowtype> FILEIN <fname>
      <flowtype> FILEIN <fname>
      ...
    END PACKAGEDATA
```

#### Explanation of Variables

##### Block: OPTIONS

  * `SAVE_FLOWS` keyword to indicate that FMI flow terms will be written to the file specified with "BUDGET FILEOUT" in Output Control.

##### Block: PACKAGEDATA

  * `flowtype` is the word GWFBUDGET, GWFHEAD, or GWFGRID.  If GWFBUDGET is specified, then the corresponding file must be a budget file.  If GWFHEAD is specified, the file must be a head file.  If GWFGRID is specified, the file must be a binary grid file.

  * `FILEIN` keyword to specify that an input filename is expected next.

  * `fname` is the name of the file containing flows.  The path to the file should be included if the file is not located in the folder where the program was run.

#### Example Input File
```
    BEGIN OPTIONS
    END OPTIONS
    
    BEGIN PACKAGEDATA
      GWFBUDGET FILEIN ../flow/mygwfmodel.bud
      GWFHEAD FILEIN   ../flow/mygwfmodel.hds
    END PACKAGEDATA
```
