Design Values ยป |

---|---|---|
The Design Values Node is used to specify the values and bounds for the key reactor design variables. The values entered here are fixed when doing a Simulation, or are considered as the initial point when optimizing the variables between the Lower and Upper Bounds.
Tabbed ViewsWhen Enable Control Profiles is enabled, and when a variable (such as Temperature, Pressure, or any Flow) is selected in the Control Profiles node, the information in Design Values for that variable is overwritten with the information in the Control Profiles subnodes.

Specifications
This displays the list of reactor variables and their bounds for each case. It is stacked in tabs together with the the Initial Charge view. The Specifications grid is organized as follows:
Initial Charge This view is stacked in tabs together with the Specifications view. As it is not shown by default, you may see it by clicking in the Initial Charge tab located at the bottom. The view displays all included cases and the list of compounds for each case. Here, you may provide the bounds and starting points for the Initial Charge of each compound into the reactor. The initial charge is fixed to the Value entered when doing a simulation. When Energy Balance is enabled in the Reactor node, Temperature also appears in this tab for each case. Temperature values and bounds correspond to the initial charge only. More information on the energy balance feature is provided in this example. Description The grid is designed similarly to its counterpart in the Estimation tree. Please see the corresponding help document. Top of Topic
Intermediate Feed
The grid is designed similarly to its counterpart in the Estimation tree, except the CSTR zones are called Process Units. Please see the corresponding help document. Top of Topic

Initialize Bounds
Top of Topic Initialize Bounds is used to fill automatically the bounds for the variables. It has two sub-actions: Current Values With this option you can autofill the minimum and maximum values with the current values. By Percent of Current This action is used to enter the bounds as percentage of the current values. On executing Initialize Bounds → By Percent of Current, a Parameters Dialog appears, requesting additional information:
