Creating the Custom Controls

Use custom controls to modify the mesh on the graphics card and to disable the prism layers in the solid regions.

Create the volume shape to refine the volume mesh near the graphics card:
  1. Right-click the Scenes node and select New > Geometry.
  2. Right-click the Geometry > Parts node and select New Shape Part > Block.
  3. In the Create/Edit Block Part in-place dialog, make the following settings in the Maximum and Minimum Coordinates box:
    Property Setting
    Corner 1 [-0.4, -0.15, -0.06] m
    Corner 2 [-0.07, -0.1, 0.07] m

    A preview of the block shape is visible in the scene.



  4. Click Create and then Close.
    The new part, Block, is added to the Parts node.
Continue by creating the volumetric control:
  1. Right-click Operations > Automated Mesh > Custom Controls and select New > Volumetric Control.
    A new node, Volumetric Control, is added to the Custom Controls node.
  2. Edit the Volumetric Control node and set the following properties:
    Node Property Setting
    Volumetric Control Parts Block
    Controls
    Prism Layer Mesher Customize Total Thickness Activated
    Values
    Custom Prism Values > Prism Layer Total Thickness Percentage of base 10.0
Create the custom control for the thin parts:
  1. Right-click Custom Controls and select New > Part Control.
    A new node, Part Control, is added to the Custom Controls node.
  2. Edit the Part Control node and set the following properties:
    Node Property Setting
    Part Control Parts Capacitor 1 to Capacitor 6
    GPU Chip
    Heatsink Block
    Memory Chip 1 to Memory Chip 8
    PCB
    Plate
    Controls
    Thin Mesher Thin Mesher Custom
    Customize Customize Thickness Threshold Activated
    Values
    Custom Thin Values > Thin Mesher Maximum Thickness Size Type Absolute
    Absolute Size 4.0 mm

    Activating the customize thickness threshold option allows you to set a custom threshold value for the thin mesher. Any part that is thinner than this threshold is meshed using the thin mesher.

Create the custom control to disable the prism layers on the parts in the solid regions and customize the surface size:
  1. Right-click Custom Controls and select New > Surface Control.
    A new node, Surface Control, is added to the Custom Controls node.
  2. Edit the Surface Control node and set the following properties:
    Node Property Setting
    Surface Control Part Surfaces Capacitor 1 to Capacitor 6
    GPU Chip
    Heatsink Block
    Inlet Fan Casing
    Memory Chip 1 to Memory Chip 8
    Outlet Fan Casing
    PCB
    Plate
    Port Block 1 to Port Block 3
    Controls
    Target Surface Size Target Surface Size Custom
    Prims Layers Prism Layers Disable
    Values
    Target Surface Size Percentage of base 25.0
  3. Save the simulation.
