Advanced Surface Freeform: Unmanned Aerial Vehicle
To achieve the desired performance for a particular application, engineers often make adjustments to small areas of the geometry, or to the entire design. In 3D-CAD, you can make these small alterations using the surface freeform operation, without exporting and reimporting the geometry into Simcenter STAR-CCM+.
Splitting the Main Body
Before you perform the freeform of the fuselage, split the body into six surfaces. The smaller surfaces reduce the computation time for the surface freeform operation and produce a more accurate surface definition.

Tutorials
Tutorials show you how to use Simcenter STAR-CCM+ for various applications in a step-by-step format with recommendations for setup, initialization and steps of the solution process specific to the application. Macro and simulation files are available for download for a large proportion of cases.
- Using Tutorial Macros and Files
  Macros, input files, and final simulation files for a range of tutorials are provided as an optional download package on the Support Center website. These macros and final simulation files are provided as an aid to the written tutorials, so that you can check your final results against the downloaded files, or against a simulation that is built and run using the macros.
- Introduction
  Welcome to the Simcenter STAR-CCM+ introductory tutorial. In this tutorial, you explore the important concepts and workflow. Complete this tutorial before attempting any others.
- Foundation Tutorials
  The foundation tutorials showcase the major features of Simcenter STAR-CCM+ in a series of short tutorials.
- Geometry
  The tutorials in this set illustrate various Simcenter STAR-CCM+ features for creating and working with parts and 3D-CAD.
  - 3D-CAD: Cyclone Separator
    Cyclone separators provide a low-cost solution for removing particulate matter from gas or liquid flows. In Simcenter STAR-CCM+, the 3D-CAD geometry modeler provides all the tools necessary for creating this type of geometry directly.
  - 3D-CAD: Freeform Surface Deformation
    Freeform surface deformation allows you to change the shape of underlying CAD surfaces. Here, you use the freeform tool to change the shape of the lower element on a rear wing from a race car.
  - Advanced Surface Freeform: Unmanned Aerial Vehicle
    To achieve the desired performance for a particular application, engineers often make adjustments to small areas of the geometry, or to the entire design. In 3D-CAD, you can make these small alterations using the surface freeform operation, without exporting and reimporting the geometry into Simcenter STAR-CCM+.
    - Importing the Starting Geometry
      You are provided a CAD model of an unmanned aerial vehicle (UAV). To manipulate the geometry using Surface Freeform, first import the CAD model into 3D-CAD.
    - Wing Freeform
      To control the deformation of the wing, you place two freeform points on the wing surface. These points are positioned at the wing tip (at the quarter chord location) and the upper surface of the wing (around two-thirds of semi-span location).
    - Stabilizer Freeform
      To provide a planar surface for the stabilizer freeform, you first split the stabilizer body into two bodies using a plane. The planar surface allows Simcenter STAR-CCM+ to produce the correct linear behavior for the surface freeform operation. To perform the surface freeform, you place a freeform control point at the trailing edge wing tip. This results in a stabilizer with a higher sweep angle and a reduced angle of attack.
    - Splitting the Main Body
      Before you perform the freeform of the fuselage, split the body into six surfaces. The smaller surfaces reduce the computation time for the surface freeform operation and produce a more accurate surface definition.
    - Nose and Camera Freeform
      Once you have separated the nose from the remainder of the fuselage, you separate it from the camera collar. To do this, create sheet bodies for the nose surfaces.
    - Propeller Freeform
      To make sure the propeller shape grows uniformly, you position two control points on the trailing edge and leading edge of the propeller blade. You then pattern the blade around the propeller hub. This produces a propeller system with three identical blades positioned equidistantly around the propeller hub.
  - 3D-CAD: Defeature and Repair using the European Truck
    In some modeling scenarios the level of detail in an imported CAD file is higher than necessary for the simulation. To simplify geometry in these cases, Simcenter STAR-CCM+ provides geometry repair and defeaturing tools within 3D-CAD, along with a shape-based search function.
  - 3D-CAD Advanced Preparation: Repairing An Exhaust
    Simcenter STAR-CCM+ provides a suite of tools in 3D-CAD that you can use to prepare and repair imported CAD geometry so that it becomes suitable for simulation. CAD geometries that are suitable for manufacturing are not necessarily ready for simulation due to the tolerances that a manufacturing process can accept.

Splitting the Main Body

Before you perform the freeform of the fuselage, split the body into six surfaces. The smaller surfaces reduce the computation time for the surface freeform operation and produce a more accurate surface definition.

In the Visualization toolbar, click (Save-Restore-Select Views) and select Views > -Z > Up +Y.
In the 3D-CAD View 1 scene, select the two faces on the underside of the model as shown below:
Right-click one of the selected faces and select Repair Tools > Split Faces By Edge Points.
Click (Save-Restore-Select Views) and select Views > -Y > Up +Z.
Select Vertex 167.
Click (Save-Restore-Select Views) and select Views > -Z > Up +Y.
Select Edge 329.
In the Split Faces By Points dialog, set the Position Along Edge to 0.37.
Click (Save-Restore-Select Views) and select Views > +Y > Up +Z.
Select Vertex 163.
Click OK.
Splitting the main body into six faces as opposed to four reduces the size of the freeform surface. A smaller freeform surface limits the overall deformation of the nose as it provides a more focused region for the operation. This also reduces the overall computation required for the operation, providing a more accurate result.
