3898	FMU co-simulation issues	richard.payne@…	Adrian Pop	"I am trying to run a co-simulation using the INTO-CPS COE and a mixture of VDM-RT, 20-sim and OM FMUs. I am using the baseline Three tank OpenModelica model in INTO-CPS SVN\WP3\T3_5_Pilot_Studies\Three Tank\Baseline\OpenModelica\Tanks and using OMEdit (v. 1.10 in the INTO-CPS 0.0.6 bundle) to export the FMUs as demonstrated in the Year 1 review video.

I have encountered a couple of issues:

1) When co-simulating using the FMU as exported I get the error: 

Failed to load and parse model defintion in: ..\ThreeTank\vOM\Tanks_Examples_WaterTanks1.fmu Reason:  Invalid ModelDescription: cvc-complex-type.2.4.b: The content of element 'InitialUnknowns' is not complete. One of '{Unknown}' is expected. at 416:23

If I uncompress the FMU and remove the 
    <InitialUnknowns>
    </InitialUnknowns>
section of the ModelDescription file, the error does not occur, but I get the next problem:

2) When changing the configuration to be the FMU with altered ModelDescription file, I simply get the error:

An FMU library didn't load
        {tank1} Load faild

Any ideas??

I have placed a version of the model with FMUs and config in Dropbox here: https://www.dropbox.com/sh/36nxcmi4cdg6tkb/AADTDPbC7Oa9z6RWGKAgYmdba?dl=0
