Building a Simple I-Spec Model
The objective of this exercise is to build a simple I-Spec model, assign a few biomarker conditions, get more familiar with the I-Spec GUI and controls, and explore some tips to increase productivity. This includes:
- Copying objects
- Snapping geometries
- Organizing components
- Renaming and editing multiple objects
We will build the model from scratch using various components such as signs, grids, boards, heat sinks, DDR memory, and flash memory.
Setting Up the Project
- Start I-Spec and create a new project.
- Set the default units:
- Go to File > Edit Reference Units > Length.
- Change the volume of lower CFM and set it as default for this project.
- Adjust display settings:
- Go to Preference > Change Display Setting.
- Set screen direction.
Adding Components
Cabinet
- Add a cabinet and apply dimensions.
Fan
- Add a fan using 2D geometry.
- Set the plane location and fix the level.
- If needed, update the plane to yc to correct the fan's orientation.
- To add more fans:
- Right-click and copy the fan.
- Create four copies and offset by -60 mm in the right direction.
Block
- Add a block and specify geometry properties.
- Select solid material and define its properties.
- If needed, create a custom material by clicking Create Material.
Heat Sources
- Add heat sources and provide their locations and names.
Network Block
- Add a network block and name it.
- Provide metric dimensions and select network registers.
- Set register values, mass, and specific heat values if required.
Heat Sink
- Add a heat sink and adjust its plane to xy.
- Use the start-end option and adjust dimensions as needed.
- Snap the heat sink onto the network block using the orange buttons.
Grouping and Editing Components
- Create groups for components like DDR RAMs and fans.
- Use multi-edit to change properties for grouped components.
- Activate or deactivate components as needed.
Finalizing the Model
- Deactivate the heat sink to evaluate system temperature without it.
- Reactivate the heat sink to compare results.
- Use the distance tool to compute distances between objects for debugging.
- Save the model as WS1 with the extension .tzr.
- Verify power values and temperature settings in the model.

This includes copying objects, snapping geometries, organizing components, renaming and editing multiple objects. We will build the model from scratch and will include various aspects such as signs, grids, boards, heat sinks, DDR memory, and flash memory.
Once you have started I-Spec, you will be able to build a new project. Set the default units by going to File > Edit > Reference Units > Length. Change the volume of lower CFM set as default for this project in Preferences. Change the display setting and screen direction. Add a cabinet.
Apply dimensions. We will add a fan using 2D geometry. Specify the plane location and dimensions. Add another fan by right-clicking and copying, creating four fans. Offset one fan -60 mm in the right direction. Add a block by clicking on the block and specifying the dimension properties.
Choose the solid material and see the conductivity. Add heat sources by providing the location and name. Choose one. Now, we will add a network block. Provide the metric dimension, select network, and specify the minimum result.
The board side, registers values, and number of registers are not required for steady state problems as an input. Add a heat sink. Change the plane to x-y. Reposition the heat sinks properly. Select heating one and use the orange buttons to snap the heat sink onto the network block.
Create groups by selecting the DDRs, right-clicking, and creating a group. You can also add fans to the group. Once you have created the groups, you can do multi-edit. Change the properties and activate/deactivate components if necessary. Change the floor for both fans. Set fixed.
Now, we will change the model object. Select memories, no flash. They should be of the same type. Load the ceramic material. To evaluate the temperature of the system, you can deactivate the heat sink and solve the case for when there is no heat sink.
Reactivate the heat sink and use the distance tool to compute the distance between objects and debug the object placement. Save the model as WS 1. Verify the power values provided. Go to Model and check the power and temperature.
The temperatures are in degrees C and the values of power are in watts. Thank you.
