 As with barrel elements, already created screw elements can be modified by opening the corresponding dialog through double-clicking the element to be edited, by selecting the icon //Edit properties of the selected element//, or by making the desired changes directly in the //Element Properties// list. As with barrel elements, already created screw elements can be modified by opening the corresponding dialog through double-clicking the element to be edited, by selecting the icon //Edit properties of the selected element//, or by making the desired changes directly in the //Element Properties// list.
  
-For seven of the ten available elements, the dialogs provide the option to define the geometry precisely through additional inputs. As an alternative to specifying the volume correction factor, the actual screw diameter and either the pitch angle or the root angle of the screw profile are entered, with the other angle being calculated automatically.+For seven of the ten available elements, the dialogs provide the option to define the geometry precisely through additional inputs. As an alternative to specifying the volume correction factor, the actual screw diameter and either the pitch angle or the root angle of the screw profile are entered, with the other angle being calculated automatically. Further details about the geometry of tightly intermeshing screw elements can be found in the reference manual (s.

-The geometry of push edge elements differs from the geometry of conveyor elements only in that it has an additional free surface. In SIGMA, this surface is characterised by two parameters, the **angle of inclination** $$\phi_s$$ and the **radius of curvature r**. Otherwise, the same specifications as for conveyor and return elements apply. +The geometry of push edge elements differs from the geometry of conveyor elements only in that it has an additional free surface.

-Unlike conveyor elements, screw mixing elements have grooves cut into their flanks. In addition to the pitch and number of grooves, the geometry of the groove in the normal section must also be defined. To ensure maximum flexibility, the geometry of the groove has been simplified by using a rectangular cross-section (characterised by groove width b and groove depth h).+Unlike conveyor elements, screw mixing elements have grooves cut into their flanks.

-Unlike conventional kneading blocks, **shoulder kneading block** have narrower kneading discs, which creates a larger leakage gap. In SIGMA, the width of the kneading discs of the shoulder kneading elements is assumed to be half the width of the conventional kneading blocks. It follows that the input masks for the two elements do not differ.+Unlike conventional kneading blocks, **shoulder kneading block** have narrower kneading discs, which creates a larger leakage gap.
