The new features and enhancements included in TAITherm v13.0 and CoTherm v2.1.

TAITherm v13.0 and CoTherm v2.1 contain several new features and upgrades that will boost your simulation capabilities and improve your workflow. Below is an overview of what we have included in the new releases. If you're interested in the updates we've made to CoTherm, you can jump to CoTherm's new features by clicking here.

Improved application performance

Application performance has been updated in this release, with improved speed of opening large files up to 50%, autoscaling transient thermal results, animating results in the post-processor and adding or deleting of parts. These updates increase productivity and create efficient use of your hardware resources. 

Improved open rates of large files

Python support for user routines

The addition of Python support enables users of this popular scripting language to create and execute scripts in TAITherm, including built-in math and physics modules. It requires less time to customize capabilities and automate processes. 


Improved script editor

Improvements have been made to the script editor including syntax highlighting and parenthesis matching, allowing you to write scripts faster and with less programming errors. 

Improvements to the script editor

Simultaneously view multiple results quantities

You can now view more than one physical quantity in the results tab at the same time. This allows you to customize the view of different heat rates for different applications and enables you to easily compare various heat rates for many layers.  

Viewing multiple variables

Updated pre-processing layout

Enjoy a streamlined workflow by specifying design temperature limits in the Editor tab instead of in the Summary table. 

Improved CFD data import

We have enhanced mesh mapping control by implementing tolerance limits, which allows you to receive a notification when the distance between thermal or CFD meshes exceed desired values. You can then choose whether to continue, stop the mapping, or use replacement values. 

Advanced solution parameters & support of parallel processing

Write intermediate results while running the distributed parallel solver and specify a much greater amount of view factors, allowing you to model higher radiation accuracy. 

Moisture Transport feature (beta test)

The new moisture transport feature enables you to track moisture transportation and accumulation. Understand how moisture moves through permeable layers, and how it accrues in layers and on surfaces. You will be able to create more accurate human models, understand latent heat in layers and model moisture storage in seat models.   

*This feature is a beta test option in this release. If you would like to join the beta test group for this feature, please contact for more information.

CoTherm improvements with this release:

OpenFOAM support

We have implemented support of OpenFOAM CFD simulation in CoTherm by adding new tool/task types and extending existing resources. Both the open-source distributions ( and and commercial distributions (iconCFD, Engys Helyx, etc.) are supported. All supported CoTherm processes can make use of OpenFOAM CFD simulations including steady or transient coupling, drive cycle analysis, and optimization. 


Fully transient thermal-CFD coupling

With this new coupling process, you can now complete fully transient thermal-CFD coupling processes in CoTherm, allowing you to capture transient fluid dynamic effects within coupled simulations. 


Selection Expression Variable for easier coupling

With the addition of the Selection Expression Variable, CoTherm allows a list of model components to be custom-formatted in any command line argument or text file. This enables user-friendly CoTherm resource inputs to be easily linked to analysis tools which are not yet natively supported. 

Scatter Plot resource

With the addition of the scatter plot resource you are now able to create plots to compare the values of different variables. This features offers insight into the relationship between different input and output variables (for example within optimization or DoE processes) which allows you to understand the influence they have on each other.  

Updated method for DOE variable specification

DoE variables can now be defined based simply on min/max values (in addition to the previous capability to reference Curve variables). You can now set up ranges for unknown variables that you would like to include in a sensitivity study in CoTherm, which extends the usability of DoE tables for more applications.
