Interactions

Within Simcenter STAR-CCM+ In-cylinder, an interaction allows you to remove volume from an Engine Part, to cut holes through Engine Parts, or to split an Engine Part Surface.

The following properties define the behaviour of an interaction:


Interaction			Example
Subtract	Allows you to remove the volume of one or more objects from the selected Engine Part. The subtracted objects are retained. Each object must share some of its volume with the Engine Part, otherwise the Engine Part remains unchanged. Solid Quick Objects Specifies the objects that remove material from the Engine Part. You can choose from Engine Parts and geometries except for sheet geometries (such as Sheet Body Rectangle).
Extrude Cut Through All	Allows you to project one or more sheet geometries in the normal direction so that they cut holes through the selected Engine Part. The three-dimensional objects that are formed by projecting the sheet geometries are subtracted from the Engine Part. Sheet Construction Geometry Specifies the geometries that determine the shape and position of the holes. You can choose from any sheet geometry or pattern of sheet geometries.
Extrude Cut Through First Segment	Allows you to project one or more sheet geometries in the normal direction so that they cut holes through the selected Engine Part. The three-dimensional objects that are formed by projecting the sheet geometries are subtracted from the first segment of the Engine Part. Sheet Construction Geometry Specifies the geometries that determine the shape and position of the holes. You can choose from any sheet geometry or pattern of sheet geometries.
Imprint	Allows you to imprint the profile of one or more sheet geometries onto the surface of the selected Engine Part. The surface is split where the new lines are added. The Engine Part and the sheet geometries must overlap by less than 1.0E-8 m, or have coincident faces, as otherwise the Engine Part remains unchanged. This property allows you to create new Engine Part Surfaces on which you can specify custom mesh settings or physics conditions. Sheet Construction Geometry Specifies the objects that imprint their profile. You can choose from any sheet geometry or pattern of sheet geometries.
