 | Types of Analyses
 | Linear heat transfer |
| Nonlinear heat transfer |
|
| State of Analyses
| Steady state heat transfer. |
| Transient heat transfer |
|
| Solution strategies
| Full and Modified Newton Raphson techniques |
| Euler Backward Implicit scheme for transient heat transfer |
| Line search option for faster convergence |
| Convergence checks on temperature and heat flow. |
|
| Elements
| Supports all available elements except those elements specialized for structural
analyses. example: Stiffness matrix, Mass matrix, Gap etc., These specialized structural
elements will be simply ignored by heat transfer analysis. |
| No need to change the element types to perform heat transfer analyses. |
|
| Analysis automatically switches to nonlinear analysis depending on the nonlinearities. |
| Time and temperature dependent properties, loads and boundary conditions. |
| Nodal loads
| Heat flow |
| Heat generation |
| Nodal temperatures |
|
| Element loads
| Convection |
| Radiation |
| Heat generation |
| Heat flux |
|
| Phase change effects
| Considers latent heat effects during a phase change in a transient heat transfer. |
| Enthalpy formulation which is not very sensitive to the phase change interval. |
|
| Initial conditions
| Prior steady state solution |
| From a user specified load set |
|
| Types of heat capacity matrices
| Lumped capacity |
| Special lumped capacity |
| Consistent capacity |
|
| Automatic transfer of results to structural analyses for thermal stress calculation |
