Objective:
Learn how to run a transient thermal analysis.
Applies to:
- Thermal Analysis
Procedure:
Note: This workflow uses Beta blocks. Learn how to turn on Beta blocks by reading: What are beta blocks?
Transient thermal analysis has the same setup as thermal analysis. Before starting, make sure you understand how to set up an analysis in nTopology. Refer to this article for more information: How can I set up a simulation?
1. Define thermal properties.
-
- Follow the steps in this article to set up your material: How to run a thermal analysis
2. Complete the FE Model and choose your Boundary Conditions.
-
- Read here for more information on thermal boundary conditions: How to run a thermal analysis.
- In this example, we use two Temperature Restraint blocks and a Surface Heat Flux block for our Boundary Conditions.
3. Run the analysis.
-
- Add a Transient Thermal Analysis block.
- This block performs a linear transient heat conduction analysis on an FE Model subject to prescribed temperature and heat flux boundary conditions.
- Set the End time. This is the time the simulation will end.
- Set the Initial time step. This sets the first step for the analysis. nTopology controls the step size for subsequent steps.
- Optional: Add a value for the Output step. This outputs the results at every Nth time iteration.
- Add a Transient Thermal Analysis block.
In this example, our Transient Thermal Analysis block has the following inputs:
Our results are shown in a Heads-Up-Display (HUD). You can visualize the Temperature, Heat Flux, and Thermal Reaction Flux in the HUD. You can access these properties by opening up the Info panel and going to the Properties tab in the Transient Thermal Analysis block.
And that’s it! You’ve successfully run a nonlinear thermal analysis.
