Build a Flow Channel with a Solid Blockage in STAR-CCM+ 3D-CAD

Build a Flow Channel with a Solid Blockage in STAR-CCM+ 3D-CAD

Overview

This tutorial explains how to create a simple flow domain with a solid blockage using Simcenter STAR-CCM+ 3D-CAD parametric modeler. 

Domain

Construct a basic flow channel that will define the domain.
  1. Right-click Geometry > 3D-CAD Models and select New.
    Figure 1
  2. Right-click YZ Plane and select Create Sketch.
    Figure 2
  3. Create a rectangular sketch on the YZ Plane offset from the Y axis. Click OK.
    Figure 3
  4. Right-click Sketch 1 and rename it to Domain.
    Figure 4
  5. Right-click Sketch Domain and select Revolve.
    Figure 5
  6. Select the following configuration and click OK:
    Figure 6
  7. Rename Revolve 1 to Domain Revolve.
    Figure 7Figure 8

Solid Blockage

Create a Solid blockage located in the middle of the flow domain. 
  1. Create a sketch on the vertical side face. Right-click side face and select Create Sketch > On Face.
    Figure 9
  2. Create enclosed shape of the face. Click OK.
    Figure 10
  3. Rename Sketch 1 to Solid.
    Figure 11
  4. Right-click Solid sketch and select Revolve.
    Figure 12
  5. Select the following configuration and click OK.
    Figure 13
    Notes
    Use Imprint as the Body Interaction type to generate geometry independently from the Domain. This method analytically projects CAD surfaces onto one another, making it ideal for high-quality models and complex curvature. It is a crucial step for creating conformal interfaces between geometric entities.
  6. Rename Revolve 1 to Solid Revolve.
    Figure 14
  7. Under Body Groups, rename Body 1 to Domain and Body 2 to Solid.
    Figure 15
    Figure 16

Fluid Volume

Create the fluid domain by subtracting the Solid blockage from Domain.
  1. Multi-select Body Groups > Domain and Solid. Right-click on the selection and select Boolean > Subtract.
    Figure 17
  2. In the Subtract panel, set Target Bodies to Domain and Tool Bodies to Solid. Check Imprint and Keep Tool Bodies. Target bodies are displayed in green while tool bodies are displayed in red.
    Figure 18
  3. Rename Domain to Fluid.
    Figure 19
  4. Rename Fluid and Solid Faces.
    Figure 20
