The Measurements Node is used to select the measured variables in the experiment sets.
Grid ViewsYou may also select variables that may be not be measured in this grid. This is useful when you are interested in seeing the evolution of these variables along with the other variables. To ensure that REX does not consider this variable for reconciliation, you should check that the variable is not selected in the Reconciled Measurements grid of the Weights node, or, ensure that the weighting factors for this variable are indeed zero. Pseudo-compounds and derived quantities may also be reconciled. To learn more about the pseudo-compound calculations at data points, please view the information provided in Note1.

Basic Measurements
This grid displays the list of variables and is organized as follows:
Note1: Pseudo-compounds and derived quantities may be reconciled only in the Total Moles series. The values of the pseudo-compounds at the datapoints are calculated as follows. Care should be taken to provide the measured values consistent with the way the calculated values are computed.

Note2: Variables such as temperature and pressure which are assumed to be uniform across the phases are available for specification only in the Total Moles / Mass series. Likewise, inflows and outflows must be specified in the Total Moles / Mass data series. Actions Merged Sets Included Sets Quick Run Open Solver
Merge Sets
When Merge Sets toggle button is active, the data for all the sets is merged into one child node Sets. When the sets are merged, you may add new experimental datapoints only with the Add Datapoint action on the Sets node . When Merge Sets toggle button is inactive, the experimental data are shown separately by set, as it is shown by default. Here, each set is a child node of this node. This action can be executed in the Measurements node, the Initialization Values node and the Profiles node. Whatever is selected in any one of these nodes results will impact in all of these nodes.
Included Sets
When Included Sets toggle button is active, it is shown only the included sets in Experiments node. if Included Sets toggle button is inactive, all sets are displayed. Top of Topic See Also: |
