Cases and Results

Cases and Results panesCases and Results panesThe design of Cases and Results pane is to allow the same setup for running ECLIPSE and Streamline simulation runs, as for running simple Volumetrics.

Workflows and Windows panes

Workflows paneStores workflows created by the Process Manager for automated processes and operations or Uncertainty workflows generated from the Uncertainty Workflow Editor.

Contains a set of variables that can be used in workflows.

Windows paneLists each window and its settings. Can be saved or deleted.

A new window is inserted from the Window menu

Object Settings – Statistics Tab The statistics for each item can be checked under the Statistics tab.

List 1Describes the X, Y, Z coordinates; Z being depth or time. If an attribute is available it will also be shown.

List 2Describes different data and values related to the object.j

One or both lists can be copied to an output One or both lists can be copied to an output sheet. Toggle on one of the lists (e.g. List 1) and click the output icon. The contents of the list will be written to an output window.

Object Settings – Colors Tab (Templates) Colors are related to the templates from Templates pane. These can be logs, depth, properties (continuous or discrete) etc.
