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?
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.
-
- You can 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.
- Initial temperature: The initial temperature of the components in the FE Model.
- Duration: Duration of the simulation.
- Initial time step: Initial time step for the transient analysis. The program will control the step size for subsequent steps.
- Save increment: Controls the amount of data that is stored and accessible after the simulation completes. The default value of 1 will save results for all increments, whereas 0 will save only the first and last increments. For any value N > 1, the block will save results for every N increment.
- Fixed time step: Option to fix the initial time step for the entire analysis. If this option is unchecked, the solver uses an automatic time-stepping scheme that varies the initial time step based on the stability of the analysis.
