getEntitiesFromSet

Overview

This utility is used for getting the actual entities from the given set. Set name is mandatory input and set type is optional.If same name is defined for different set type (Nodes, shell elements, solid elements, solid element face), then defining the set type will be useful to get the entities from the specified type.

Syntax

Without set type

EntityIdArray=simlab.getEntitiesFromSet('SetName');

With set type

EntityIdArray=simlab.getEntitiesFromSet('SetName', 'SetType');

where,

• SetType = Node; to get node set entities
• SetType = Shell_Elem; to get shell element set entities
• SetType = Solid_Elem_Face; to get solid element face entities
• SetType = Solid_Elem_Layer; to get solid elements set entities

User Case

• To create the new body for the specified layer of solid elements attached to the face of the parent body

Why we need this utility?

For above case, we will use 'Create body from Solid element' tool to create the new body by giving solid elements in solid element set as input. When we recorded this operation using Project > Record, the solid element Ids will be hardcoded in script. When we use this script for different models, it will fail due to difference in solid element IDs. In order to overcome this, we can make use of this utility to extract the solid elements from solid element set and utilize it for different models.

Utility Input/output

Without set type

With set type

Hint

After extracting the Entity ids, convert it as a string by adding "str" and remove the () using ".strip" and store it in a variable for ease of use.Entity_Id=str(Entity_Id).strip("()")
