Note: The Nonlinear Thermal Analysis block is a BETA block.
The inputs for the block include:
  • FE Model
  • Boundary Condition Listwith the restraints and applied thermal loads
  • Maximum iterationsto run the analysis
  • Solution convergence as a tolerance value to stop the analysis where there is a converged result based on a comparison of the Euclidean norm of the solution updated vector of the temperature (K) with the specified tolerance value. The default value is 0.001 K
  • Reaction Convergenceas a tolerance value to stop the analysis where there is a converged result based on a comparison of the Euclidean norm of the solution updated vector of the power (W) with the specified tolerance value. The default value is 5000 mm2s-3kg
  • Output stepto output the results at every nth output step (optional input)
The block automatically runs when the necessary inputs are complete. Before running the Nonlinear Thermal Analysis, you must correctly define the nonlinear material property as discussed in the lesson on Thermal Material Properties. After defining the material property correctly in the FE Model (as was shown for a Thermal Analysis), and defining the boundary conditions, a Nonlinear Thermal Analysisis run as shown below.
