Part Creation Options Dialog

Create Parts From Solids	Only solid bodies are used to create parts. By selecting both Create Parts From Solids and Create Parts From Sheets parts are created using both solid and sheet bodies.
Create Parts From Sheets	Only sheet bodies are used to create parts. By selecting both Create Parts From Solids and Create Parts From Sheets parts are created using both solid and sheet bodies.
Create As Mesh Parts	Allows you to convert all the solid and sheet bodies selected into faceted bodies and sheets. These faceted bodies and sheets are then transferred as mesh parts.
Mark Feature Edges	This option allows you to specify which of the mesh edges that lie along CAD edges are marked as feature edges. CAD edges are the edges or curves that belong to the underlying CAD model; mesh edges are the line segments that bound the mesh faces.
No CAD edges	Does not mark any mesh edges as feature edges.
Sharp CAD edges	Marks any mesh edge that lies along a sufficiently sharp CAD edge (based on the Sharp Edge Angle value) as a feature edge. For any given CAD edge, either all or none of the mesh edges that lie along the CAD edge are marked as feature edges.
All CAD edges	Marks all mesh edges that lie along any CAD edges as features edges.
Sharp Edge Angle (deg)	Allows part curves to be created based on a supplied angle. The default angle is 30 degrees.
Create Part Contacts from Coincident Faces	Activating this option causes Simcenter STAR-CCM+ to search for coincident faces in the 3D-CAD geometry. For each pair found, part contact data is created and stored in the Contacts property of each part. See Creating Part Contacts From Coincident Faces.
Create Parts From Faceted Solids	Converts any selected faceted solids to mesh parts.
Create Parts From Faceted Sheets	Converts any selected faceted sheets to mesh parts.
Part Type	CAD Part with 3D-CAD Association	Creates part with full 3D-CAD association. All named faces are associated with the part surfaces. If you modify a geometry in the 3D-CAD modeler, the model is marked as "dirty" or out-of-date, and when you update it, the relevant changes from 3D-CAD are pushed to parts level.
CAD Part without 3D-CAD Association	Creates CAD part with just underlying CAD geometry and no association with 3D-CAD. If you modify a geometry in the 3D-CAD modeler, the model is not flagged as "dirty" or out-of-date and you cannot update the part from 3D-CAD.
Mesh Part with 3D-CAD Association	Creates a mesh part without any CAD data attached to the part. However an association with 3D-CAD is maintained. If you modify a geometry in the 3D-CAD modeler, the model is marked as "dirty" or out-of-date, and when you update it, the relevant changes from 3D-CAD are pushed to parts level.
Mesh Part without 3D-CAD Association	Creates a mesh part without any CAD data attached to the part and has no association to 3D-CAD. If you modify a geometry in the 3D-CAD modeler, the model is not flagged as dirty or out-of-date and you cannot update the part from 3D-CAD.
Create Shells From Sheets	When activated, Simcenter STAR-CCM+ converts any sheet bodies into shell parts rather than regular parts.
Coincident Face Tolerance	When the Create Part Contacts from Coincident Faces option is activated, part contact data is generated for parts that share coincident faces that are within the Coincident Face Tolerance distance from their neighbors. This option is intended to close small, erroneous gaps in imported geometries. Do not change this value specifically to create contacts or interfaces between parts that have large gaps between them. If parts have large gaps between them, move one part closer to the other using a translation operation.
Tessellation Density	This option determines the level of surface refinement that Simcenter STAR-CCM+ uses when creating the geometry part, and affects the degree to which surface curvature is preserved in the created part. In general, it is recommended that you start by using one of the coarse options, then review the surface triangulation to see if the geometry part needs to be retessellated with a higher density. See Retessellating a Part. For geometries with high amounts of curvature, and for which a higher surface fidelity is desired, one of the finer options is recommended. The tessellation density option has no effect on planar surfaces—the same triangulation is obtained for these surfaces regardless of the settings used.
Very Coarse	Uses the least number of triangles to discretize a curved surface.
Coarse	Uses fewer triangles to discretize a curved surface.
Medium	Uses the default number of triangles to discretize a curved surface.
Fine	Uses more triangles to discretize a curved surface.
Very Fine	Uses the most number of triangles to discretize a curved surface.
Show Detailed Tessellation Parameters	Activating this option displays detailed tessellation Parameters within the Part Creation Options dialog. You can then edit these Detailed Tessellation Parameters as required.

Create Parts From Solids

Only solid bodies are used to create parts. By selecting both Create Parts From Solids and Create Parts From Sheets parts are created using both solid and sheet bodies.

Create Parts From Sheets

Only sheet bodies are used to create parts. By selecting both Create Parts From Solids and Create Parts From Sheets parts are created using both solid and sheet bodies.

Create As Mesh Parts

Allows you to convert all the solid and sheet bodies selected into faceted bodies and sheets. These faceted bodies and sheets are then transferred as mesh parts.

Mark Feature Edges

This option allows you to specify which of the mesh edges that lie along CAD edges are marked as feature edges. CAD edges are the edges or curves that belong to the underlying CAD model; mesh edges are the line segments that bound the mesh faces.

No CAD edges

Does not mark any mesh edges as feature edges.

Sharp CAD edges

Marks any mesh edge that lies along a sufficiently sharp CAD edge (based on the Sharp Edge Angle value) as a feature edge. For any given CAD edge, either all or none of the mesh edges that lie along the CAD edge are marked as feature edges.

All CAD edges

Marks all mesh edges that lie along any CAD edges as features edges.

Sharp Edge Angle (deg)

Allows part curves to be created based on a supplied angle. The default angle is 30 degrees.

Create Part Contacts from Coincident Faces

Activating this option causes Simcenter STAR-CCM+ to search for coincident faces in the 3D-CAD geometry. For each pair found, part contact data is created and stored in the Contacts property of each part. See Creating Part Contacts From Coincident Faces.
