Track Nodes with Slowest Convergence Each Iteration
Use the ‘write maximum temperature change per iteration’ option while running in distributed parallel. Find the nodes with the highest tolerance in each iteration and write them out to a text file, which will help to debug models that are converging slowly or diverging.
Improved Transient Model Stability
The multigrid solver now provides improved stability for some transient models – especially those using exhaust streams with changing mass flow rates.
Import CFD Data from CSV Files with Custom Headers
You can now customize column headers in the CSV point cloud file when importing CFD data. This simplifies the process when reading in data from different CFD solvers by removing the requirement of using a fixed set of column headers.
Increase Accuracy with Multivariable Drive Cycle CFD Interpolation Settings
Two new interpolation options were added for the inverse distance weighting method. Apply imported CFD to a thermal model when they are associated with multiple independent variables (CFD records may be associated with a time value, a speed value, or multiple values associated with curves). This provides more accurate results when more than two independent variables are used.
Report Advanced Solver Parameters to Messages Window or Console
Your solver option will now be printed in the Messages window or console when running a thermal analysis. If you are using the ‘Multigrid’ option, all of the multigrid solver settings will also be reported.
Applications and packaged utilities now share a versioning scheme of <Year>.<Major Release>.<Minor Release>, helping to clarify the origin, currentness, and compatibility of the applications. The branding on application icons and splash screens has also been updated.
