Hello all,

 

I am using UniSims "USE-IT" excel interface to update a unisim case with values from Excel. I'm able to do this for most object properties, but some give me errors. Specifically, trying to specify a heat exchangers UA value gives me an input error.

 

Here is the input XML:

<UnisimTag uopCaption="UA" uopUnisimObjectName="E-0301.UA" uopUnisimObjectPath="oUnisimSimCase.flowsheet.Operations.item('E-0301').UA"/>

 

The error is:

Error in unisimIO.Execute_Batch:
Invalid input for oUnisimSimCase.flowsheet.Operations.item('E-0301').UA Error text:uopUnisimEvaluator::SetValue error - description: [object Error] - code: oUnisimCase.flowsheet.Operations.item('E-0301').UA.SetValue(100, "kJ/C-h") code: oUnisimSimCase.flowsheet.Operations.item('E-0301').UA: 2014-01-24 8:48:29 PM
 

 

I know it's a long shot, but I'm completely stuck, any help would be just awesome.

 

Thanks,

-Cole

I used HYSYS but version 10 years old. Nothing like this easy stuff was available, so I fetched values with vba code. Surely there is a user manual available. AspenTech has good support site with examples. Maybe Honeywell has something similar? I do remember that not all values were exposed in HYSYS, so there was a "backdoor" method. Maybe you are seeing one of these. I know for LNG exchanger I had to fetch UA values backdoor. If this is the case, you will need to resort to the old fashioned, but reliable, OLE with vba. Or, it's just the syntax you have to get right. Good luck.
