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.

Generating the Volume Mesh

Set up and generate the volume mesh.

Right-click the Geometry > Operations node and select New > Mesh > Automated Mesh.

In the Create Automated Mesh Operation dialog:

Select Fire and Room from the Parts list.

Select the following meshers, in order:


Group	Mesher
Surface Meshers	Surface Remesher
Core Volume Meshers	Polyhedral Mesher
Optional Boundary Layer Meshers	Prism Layer Mesher

Click OK.

An automated mesh operation is added to the Operations node.

Select the Automated Mesh > Default Controls > Base Size node and set Base Size to 0.1 m.
Select the Default Controls > Minimum Surface Size node and set Percentage of Base to 50.0.
This change prevents the mesher from creating small cells within the fire part.
Deactivate prism layers on the interface between the fire and the room:
1. Right-click the Automated Mesh > Custom Controls node and select New > Surface Control.
2. Select the Custom Controls > Surface Control node and set Part Surfaces to Fire.Interface and Room.Interface.
3. Select the Surface Control > Controls > Prism Layers node and set Prism Layers to Disable.
Force the volume mesher to create cells within the fire part that are similar in size to cells in the rest of the mesh:
1. Right-click the Automated Mesh > Custom Controls node and select New > Part Control.
2. Select the Custom Controls > Part Control node and set Parts to Fire.
3. Select the Part Control > Controls > Volume Growth Rate node and set Volume Growth Rate to Custom.
4. Select the Part Control > Values > Volume Growth Rate node and set Volume Growth Rate to 1.0.

Generate the volume mesh:

Click (Generate Volume Mesh).
When the volume mesh is generated, the message Volume Meshing Pipeline Completed is displayed in the Output window. The numbers of Cells, Faces, and Vertices are also reported.
Create a mesh scene.

The volume mesh is displayed below.
