Graphics Card

Define the geometry, placement, and physics of the graphics card using Custom PCB, Chip, Heatsink, and Generic QuickParts.

To define the printed circuit board:
  1. Right-click the QuickParts node and select New QuickPart > PCB > Custom.
  2. In the Select Construction Geometry dialog, select PCB and click OK.
  3. Right-click the QuickParts > PCB node and select Edit.
  4. In the Edit dialog, set the following Physics properties:
    Property Setting
    Thermal Specification Specify By Layer
    PCB Normal [0.0, 1.0, 0.0]
  5. Set the metal fractions of the layers to the following values:
    Name Thickness Metal Fraction
    Layer 1 0.25 mm 0.3
    Layer 2 1.5 mm 0.001
    Layer 3 0.25 mm 0.3
  6. Click Apply, then Close.
To define the memory chips and the GPU chip casing:
  1. Right-click the QuickParts node and select New QuickPart > Chip > Custom.
  2. In the Select Construction Geometry dialog, select GPU Chip and all memory chips, that is Memory Chip 1 to Memory Chip 8.
  3. Click OK.
    A total of nine Chip QuickParts are created.
  4. Right-click the QuickParts > Chip node and select Edit.
  5. In the Edit dialog, set Name to GPU Chip Casing.
  6. Set the following Physics properties:
    Property Setting
    Material Si
    Heat Source 25.0 W
  7. Click Apply, then Close.
  8. Multi-select the QuickParts > Chip 2 to Chip 9 nodes, right-click and select Edit.
    To select multiple nodes hold down the <Ctrl> key.
  9. Set the following Physics properties:
    Property Setting
    Material Si
    Heat Source 4.0 W
  10. Click Apply, then Close.
Organize the memory chips in an assembly:
  1. Multi-select the QuickParts > Chip 2 to Chip 9 nodes, right-click and select Composite.
  2. Right-click the QuickParts > Composite node, select Rename..., and enter the name Memory Chips.
To set up the capacitors:
  1. Right-click the QuickParts node and select New QuickPart > Generic > Custom.
  2. In the Select Construction Geometry dialog, select all capacitors, that is Capacitor 1 to Capacitor 6, and click OK.
  3. Multi-select the QuickParts > Generic to Generic 6 nodes, right-click and select Edit.
  4. In the Edit dialog, click the Material > Solid box and select Alumina.
  5. Click Apply, then Close.
  6. Multi-select the QuickParts > Generic to Generic 6 nodes, right-click and select Composite.
  7. Rename the Quick Parts > Composite node, Capacitors.
To set up the connector port blocks and the back plate:
  1. Right-click the QuickParts node and select New QuickPart > Generic > Custom.
  2. In the Select Construction Geometry dialog, select Port Block1, Port Block 2, Port Block 3, and Plate and click OK.
  3. Rename the QuickParts > Generic node, Back Plate.
  4. Multi-select the QuickParts > Generic 2, Generic 3, and Generic 4 nodes, right-click and select Composite.
  5. Rename the QuickParts > Composite node, Connector Port Blocks.
To set up the heat sink:
  1. Right-click the QuickParts node and select New QuickPart > Heatsink > Custom.
  2. In the Edit dialog, within the Geometry section, click the Base box and select Heatsink Block.
  3. Click OK.
The components of the graphics card are now set up. Finally, organize the components in an assembly:
  1. Multi-select all QuickParts in the tree, right-click and select Composite.
  2. Rename the QuickParts > Composite node, Graphics Card.
  3. Save the simulation .
