Resistance Wire
This simulation tutorial will walk you through the following:
- Customizing your material.
- Applying thermal convection, power, and radiation boundary conditions.
- Viewing the temperature distribution in the simulation results
Import the CAD file
- In OnScale Solve, from the Projects tab of the dashboard, create a new project.
- In the ToolBar, click (+) and then Library. Within the OnScale Library, Select Resistance wire.
Assign a material
- Using the Model tree, select the Resistance wire.
- From the Material dropdown in the properties panel, select Create Material.
- Rename the Material Name to Constantan.
- Enter the properties in their various dialog boxes as shown below:
Properties | Value |
Mass Density (kg/m3) | 8885 |
Poisson’s Ratio | 0.3 |
Young’s Modulus (Pa) | 162e6 |
Specific Heat (J/(kg*K)) | 410 |
Thermal Conductivity (W/(m*K)) | 23 |
Thermal Expansion (1/K) | 13.5e-6 |

Add a power source
- Select the
tab.
- In the toolbar ensure that the Mechanical Physics is toggled off, and enable Thermal Physics.
- Select the Thermal icon
, then select Power load.
- Select the Resistance wire part from the Model tree.
- Enter 3.2 W in the Power property panel, then select Done.
Thermal Environment settings
- Click on Thermal Environment.
- Click on edit.
- Enter 26.85 C as the Ambient temperature.
Add the convection coefficient
- Select the Thermal icon
, then select the Convection constraint.
- Using the Model tree, click on the dropdown arrow within the Resistance wire.
- Select all three faces of the resistance wire.
- Enter 100 under the Convection Coefficient field of the properties panel. Then, select Done.
Add radiation
- Select the Thermal icon
, then select the Radiation constraint.
- Using the Model tree, click on the dropdown arrow within the Resistance wire.
- Select all three faces of the resistance wire.
- Enter 0.8 under the emissivity field of the properties panel.
- Enter 26.85 as the Far-Field temperature. Then, select Done.
Run a simulation
- Select the simulator tab.
- Click on the Launcher to run the simulation
- Once the meshing and estimation is complete, Select Launch to run the simulation study.
Analyze the results
- Once the simulation has finished, select Load Results to open the results in the Results tab.
- Temperature will be the selected dataset for the Thermal simulation.
- Expand the Settings option and toggle Show Mesh on.
- What is the maximum operational temperature on the wire in degrees Celsius?
- Would the resistance wire fail?
