Mixture Selections Chapter
Applicability: Synapse (core versions 0315+)

In a mixture selection, you first specify a set of constraints on physical properties. Then, Synapse examines every mixture in a selected knowledge base identifying those mixtures which possess physical properties that satisfy your input constraints.

The Mixture Selections Chapter is found in mixture selection documents. The chapter stores constraints and selection results.

Chapter Sections

The chapter's datapane is divided into five sections:

Section Description
Source Knowledge Base Section used to record the knowledge base that will be used as the source of all mixture candidates, physical property data and estimation techniques.
Constraints Section contains one large field used to the store and edit the physical property constraints used to constrain the selected mixture candidates.
Candidates Section displays the mixture candidates and their constraint evaluation results in tabular and graphical formats.
General Notes Section used to store general notes about the current selection. Often a brief summary of the selection's objective is entered in this field.
Associated Documents Section used to store links to any documents associated with the current selection.
Chapter Commands

The Mixture Selections chapter has commands for reporting results and selecting mixtures. These commands are available from the chapter's Commands menu.

  • Open Source Knowledge Base: opens the knowledge base stored in the source knowledge base section.
  • Test Selection Constraints: prompts for the selection of a mixture and then activates the Mixture Candidate Detail Dialog which shows the results of applying the constraints to the selected mixture. This command is very useful for checking that the selection's constraints were entered correctly.
  • Report Selection Properties: activates the Report Properties Dialog that enables you to select selection attributes and results to add to an open Report Document. (Also see documentation on Reporting Properties.
  • Save Mixtures Ranking: activates the Mixture Ranking Dialog that enables you to add each mixture's rank in the current selection as an Undesignated Property of the mixture in the associated knowledge base.
  • Select Mixtures: activates the Mixture Select Dialog. Synapse will automatically estimate the physical properties of each mixture found in the source knowledge base and use these values to evaluate each selection constraint.
Common Commands

The menubar provides numerous other commands for navigation, bookmarking, file operations, units conversion, etc. See the documentation on Common Commands for details.
