          Parameters
          ----------
          elemShape2D
              A SymbolicConstant specifying the default element shape for meshing two-dimensional 
              objects. Possible values are QUAD, QUAD_DOMINATED, and TRI. The default value is 
              QUAD_DOMINATED. 
          elemShape3D
              A SymbolicConstant specifying the default element shape for meshing three-dimensional 
              objects. Possible values are HEX, HEX_DOMINATED, WEDGE, and TET. The default value is 
              HEX. 
          quadAlgorithm
              A SymbolicConstant specifying the default algorithm for meshing an object with quad- or 
              quad-dominated elements. Possible values are ADVANCING_FRONT and MEDIAL_AXIS. The 
              default value is ADVANCING_FRONT. 
          allowMapped
              A Boolean specifying whether Abaqus/CAE should allow mapped meshing, where appropriate. 
              The default value is OFF. 
          minTransition
              A Boolean specifying whether Abaqus/CAE should attempt to minimize the mesh transition 
              when it moves from a coarse mesh to a fine mesh. The default value is ON. 
          guiPreferredElements
              A list of SymbolicConstants specifying preferred Abaqus element types. This setting is 
              relevant only when Abaqus/CAE is run interactively. When a part or part instance that 
              has never been assigned an element type is meshed, this list is consulted. If an element 
              type appropriate to the geometry is found in the list, it is assigned to the geometry. 
              Multiple element types representing different shapes (for example, triangles and 
              quadrilaterals) can be assigned in combination, but only element types that are 
              compatible with each other are used. When more than one appropriate element type is 
              found in the list, the first element type encountered takes precedence. This list is 
              also consulted when populating the element type dialog; preferred types are selected by 
              default for a region not previously assigned any element types. The default value is an 
              empty list.
