Element Type & Control

Hey,
I noticed that pyprime works so well I don't have to think about the element type in pymapdl. Then I realized, I always need to think about element type in FE.
What is the logic of the default elements when generating a cdb and is there any way to control the element types?

Start by tracing how pyprime generates a CDB and how pymapdl represents element types. Determine where the default element selection is defined and whether an existing control point is exposed. Done means documenting the default logic and establishing a clear way to control the generated element types.
