- Introduction to TMG Correlation
- TMG Correlation workflow
- TMG Correlation interface
  The TMG Correlation user interface is integrated in Simcenter 3D using NX Open and contains unique features to conduct a thermal correlation analysis, in addition to standard tools and commands described in the Simcenter 3D Online help and the NX Online help.
- Thermal correlation analysis preparation
  Before conducting a thermal correlation analysis, it is important to properly prepare your simulation model and the reference data.
- Understanding thermal correlation analysis
  The thermal correlation is a calibration process that helps you find the best thermal solution that minimizes the error between the computed and target temperatures at different locations and times.
- Managing the reference data
  In TMG Correlation, reference data refers to the temperature and time data that come from experimental tests or from prior and validated simulation models. They are named sensors and are used as targets for the optimization of the correlated solution.
- Understanding design variables
  A design variable is a simulation entity of your model that the TMG Correlation solver varies within a specific range during the optimization to reduce the gap between the reference data and the simulation results.
- Setting up the optimization
  In optimization, the goal is to find values for the design variables that minimize the difference between the reference data and the correlated solution results.
- Monitoring the optimization
  Use the Solution Monitor and Solution Control Monitor to track the analysis during the solve. The monitors provide solver-specific information for the TMG thermal solver and the thermal correlation analysis.
- Analyzing the optimization results
  After you solve a thermal correlation analysis, you can analyze the results of the optimization process in the TMG Correlation dialog box.
  - Compare reference and optimized temperatures
    The following example shows how to plot the reference, original, and optimized temperature values for two sensors after solving a thermal correlation analysis.
  - Display results information
    Use the following procedure to display information for each target after the optimization of a thermal correlation analysis.
  - Results page
    The Results page displays the results of the optimization procedure for the thermal correlation analysis when you select the Results node in the main panel.
- Updating the simulation model
  After you verified the optimization results, you must update the simulation model to reflect any changes that were made during the thermal correlation analysis so that you can continue your modeling in Simcenter 3D.

Analyzing the optimization results

After you solve a thermal correlation analysis, you can analyze the results of the optimization process in the TMG Correlation dialog box.

To see if the optimization results fulfill your requirements, you can:

Plot the optimized solution temperatures against the sensor data and the original solution temperatures. This plot shows the overlay of the reference, original, and optimized temperatures for one selected target.
Inspect the optimization convergence. For example, the final value of the objective function and number of design cycles.
Inspect the final values of the optimization design variables.
Modify your thermal correlation analysis and solve the optimization again until you get the desired results.
