Car Mesh

1. Select General Mesher in the Mesh Panel.
2. Enter car under Mesh Name in the Properties Panel.
3. Select all CAD Surfaces in the Geometric Entities Panel and click Add Surfaces icon for CAD Surfaces in the Properties Panel.
4. Enter the Maximum Cell Size as 0.01, Minimum Cell Size as 0.0007 and Cell Size on Surfaces as 0.01 .
5. Click Create Mesh. A new mesh car is created under Built Meshes in the Geometric Entities Panel.
6. The meshed Volume car is generated under Volumes.

To generate a mesh for windshield and ice Volume, the Layer option is used.

1. Select Template Mesh/Surface in the Mesh Panel.
2. Select Layer from the Shape drop-down list in Geometry Tab of Properties Panel.
3. Enter windshield for Mesh Name.
4. Select windshield from the Boundaries list under car Volume in the Geometric Entities Panel.
5. Click Add Surfaces icon for Surfaces in the Properties Panel.

6. Enter the parameters as follows:

   • Thickness: 0.005 m
   • Cell Size on Wall: 0.00025 m
   • Number of Layers: 20 under Cluster Options for Exponential
7. Click Build Layer Mesh. The new mesh windshield is created under Built Meshes in the Geometric Entities Panel.
8. The meshed volumes windshield is generated under Volumes.

To generate a mesh for ice Volume, the Layer option is used.

1. Select Template Mesh/Surface in the Mesh Panel.
2. Select Layer from the Shape drop-down list in Geometry Tab of Properties Panel.
3. Enter ice for Mesh Name.
4. Select windshield_top from the Boundaries list under windshield Volume in the Geometric Entities Panel.
5. Click Add Surfaces icon for Surfaces in the Properties Panel.

6. Enter the parameters as follows:

   • Thickness: 0.001 m
   • Cell Size on Wall: 0.00025 m
   • Number of Layers: 4 under Cluster Options for Exponential
   • Select Yes for build_on_thin_cells drop-down
7. Click Build Layer Mesh. The new mesh ice is created under Built Meshes in the Geometric Entities Panel.
8. The meshed volume ice is generated under Volumes.

Default Interfaces

Interfaces are automatically created between the volumes.

Seperate interface

1. Select inlet from the Interfaces list under car Volume in the Geometric Entities Panel.
2. Select Split/Combine Geometry or Grid under Mesh Panel.
3. Select Separate Interface under Operation drop-down list in the Properties Panel.
4. Click Separate Interface. Two new Boundaries inlet_i1 and inlet_i2 are created under Boundaries list of car Volume.
