Sources manager (load case filtering)
The user interface for selecting geometry and FE entities for a calculation is called the sources manager. The sources manager is incorporated into the dialog boxes that you use to:
Create calculations
Extract loads for calculations
Extract physical properties such as length and thickness for calculations
The sources manager is contained in the following locations:
The Sources group of the Calculation Creation, Calculation Editor, Calculation Copy Editor, and Property Extractor dialog boxes.
The Selection group of the Load Extraction dialog box.
With the sources manager, you can:
Access numerous options for selecting geometric and FE entities.For example, the sources manager supports groups and selection recipes.
Create multiple sources.For example, you can extract each stress for a calculation from a different source and you can extract the properties that define calculation parameters from other sources.
Edit the contents of an existing source.For example, you can add entities to an existing source, or you can replace all entities in an existing source.
