- 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.
- 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.

Introduction to TMG Correlation

TMG Correlation is a Maya HTT product that allows you to calibrate a Simcenter 3D thermal model by minimizing the error between the computed temperatures, and reference temperatures coming from test data or validated simulation results. It supports steady-state and transient solutions, including an unlimited number of design variables and sensors in the reference data, which allows you to perform a thermal correlation analysis.

TMG Correlation is fully integrated in Simcenter 3D and requires the Simcenter 3D Pre/Post application.

The following flowchart illustrates the TMG Correlation solution process:

Using TMG Correlation, you can:

Compare a Simcenter 3D solution with reference data from tests or experiments, and then calibrate the original solution to match the reference data.
Compare a Simcenter 3D solution with reference data from theory, third-party simulations, or an existing Simcenter 3D simulation, and then calibrate the original solution to match the reference data.
Calibrate a Simcenter 3D solution using temperature targets based on certification or industry standards such as RTCA DO-160G or ECSS Thermal Control General Requirements, ECSS-E-ST-31C.
