MATLAB - HYSYS Column feed control

I suceed to connect MATLAB(R2015b) - HYSYS(ver7.3). I can control temperature, pressure,etc via MATLAB. I can change total stage number of column and reset/run is also ok to control. BUT I cannot change optional feed stage.

my code is as below.

 hCase = h.ActiveDocument;
 Column = hCase.Flowsheet.Operations.Item('T-100');  %column name is T-100
 Columnflowsheet = Column.ColumnFlowsheet;
 ColumnOptionalFeedStage1 = Columnflowsheet.FeedColumnStages.Item(1).StageNumber;
 ColumnOptionalFeedStage2 = Columnflowsheet.FeedColumnStages.Item(2).StageNumber;

ColumnOptionalFeedStage1 and 2 are internal real variable.(Library Columnstage)

Command

 ColumnOptionalFeedStage1.Value

show me the value. So far good.

I WANT TO CHANGE ITS VALUE. THAT MEANS I WANT TO CHANGE FEED STAGE NUMBER WHICH IS INTEGER.

however,

 ColumnOptionalFeedStage1.SetValue(3)
 ColumnOptionalFeedStage1.Value = 3

both above does not work.

HOW CAN I CHANGE FEED STAGE?

OR

WHERE CAN I LOOK HYSYS 7.3 LIBRARY? (In MATLAB - Excel interface, navigation through library is possible. I can see all possible sysntax. where in MATLAB?)

[Eng]

any body know that?

Hi,

Try:

hCase = h.ActiveDocument;

Column = hCase.Flowsheet.Operations.Item('T-100'); %column name is T-100

ColumnOptionalFeedStage1 = Column.ColumnFlowsheet.FeedStreams.Item('1');

ColumnOptionalFeedStage2 = Column.ColumnFlowsheet.FeedStreams.Item('2');

Column.ColumnFlowsheet.Operations.Item("Main_TS").SpecifyFeedLocation(ColumnOptionalFeedStage1, 48); % 48 is the Feed Location

Column.ColumnFlowsheet.Operations.Item("Main_TS").SpecifyFeedLocation(ColumnOptionalFeedStage2, 48); % 48 is the Feed Location

Best Regards.
