# Transient Thermal Analysis

Perform a transient heat conduction analysis on an FE Model subject to temperature and heat flux boundary conditions.

### Inputs

| Name | Type | Description |
| - | - | - |
| Model | [FE Model](../../../../block-documentation/types/fe-model) | The finite element model. |
| Load case | [Boundary Condition List](../../../../block-documentation/types/boundary-condition) | The restraints and applied thermal loads. |
| Initial temperature | [Temperature Field](../../../../block-documentation/types/temperature-field) | The initial temperature of the domains in the FE Model. |
| Duration | [Scalar](../../../../block-documentation/types/scalar) | Duration of the simulation |
| Initial time step | [Scalar](../../../../block-documentation/types/scalar) | Initial time step for the transient analysis. The program will control the step size for subsequent steps. |
| Save increment | [Integer](../../../../block-documentation/types/integer) | 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 a value of 0 will save only the first and last increment. For any value, N > 1, the block will save results for every N increments. |
| Fixed time step | [Bool](../../../../block-documentation/types/bool) | 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. |

### Outputs

| Type |
| - |
| [Time Dependent Thermal Result](../../../../block-documentation/types/time-dependent-thermal-result) |
