TAITherm 2025.1 Release
TAITherm 2025.1 takes a significant leap
forward in its ability to seamlessly integrate with third-party tools, enabling
efficient multi-physics simulations across various scales. This release builds
upon previous advancements in Functional Mockup Unit (FMU*) export and
Input/Output Parameter coupling, unlocking new possibilities for human and
battery thermal simulations. *See fmi-standard.org for more
information.
Smarter Cabin Simulations with Human
Thermal Integration: Understanding and optimizing cabin
comfort just got a whole lot more sophisticated. TAITherm 2025.1 now allows you
to incorporate the human element directly into your simulations.
Whole
Body Thermal Sensation and Comfort as Output Parameters: Cabin simulations
are now enhanced by taking the human occupants into account. The
whole-body thermal sensation and comfort results are available in Output
Parameters and exposed on the Functional Mockup Interface (FMI) so that
they can be coupled into system modeling tools for the development of
comfort-based HVAC controllers. Imagine HVAC systems that respond not just
to a target temperature, but to how the occupants feel.
Anticipating
Occupant Behavior: This capability opens the door to simulating occupant
behavior over long transient events. A cold occupant is likely to increase
the heating, while a warm one will adjust it down. This release provides
access to the whole-body comfort and sensation.
Foundation
for Microclimate Optimization: While this release focuses on whole-body
comfort, future iterations will provide access to body segment-level
results, paving the way for optimizing microclimate devices like heated
seats and radiant panels with unprecedented precision.
Enhanced Battery Thermal Management for
Hybrid and Electric Vehicles: Efficient
battery thermal management is critical for the performance and longevity of
hybrid and battery electric vehicles. TAITherm 2025.1 strengthens the link
between battery thermal models and Battery Management System (BMS) simulations.
Battery
Electrical Load as an Input Parameter: You can now directly set the
battery electrical load fr|om an Input Parameter, allowing for dynamic
coupling with BMS simulations in system-level tools.
Seamless
Data Exchange: Existing Output Parameter types can then be used to send
crucial thermal results, such as battery cell temperatures, back to the
system simulation environment. This tight integration enables more
accurate and comprehensive analysis of battery performance under various
operating conditions.
Improved Human Thermal Model Workflow: Managing
complex human thermal models is now more intuitive and robust.
Body
Part Map Integrated into TDF File: The definition of body parts and their
corresponding segments is now stored directly within the TAITherm Data
File (TDF). This integration streamlines workflows and allows for earlier
error detection during the model check process within the user interface.
Issues that previously might only surface during the thermal solution
phase can now be identified and resolved proactively.
Automatic
Body Part Map Synchronization: Operations that previously could lead to
part ID renumbering, such as appending a human model into a cabin model,
will now automatically update the body part map, ensuring data integrity
and saving valuable user time.
Backward
Compatibility and Flexibility: For users who prefer the traditional
method, the body part map can still be exported and imported as a text
file fr|om the human dialog or via the command line.
RapidFlow’s Enhanced User Experience: RapidFlow
continues to evolve with user-centric improvements and powerful new
capabilities for simulating multiple fluid domains.
GUI
Enhancements: Enjoy a smoother and more efficient workflow with
refinements to the RapidFlow user interface.
Introducing
Multiple Fluid Domain Simulation: Fluid domains are still defined within a
model using Fluid Parts, but now, rather than that fluid part having a
required special name and only being able to have one of them, there is a
checkbox to indicate which fluid parts are used to define RapidFlow
domains.
Improved
Error Checking: Benefit fr|om clearer and more informative feedback on
setup issues, making it easier to identify and resolve configuration
problems.
More
Robust Fluid Volume Meshing: The fluid volume mesher is now more tolerant
of small gaps in the bounding geometry, reducing the likelihood of
unintended fluid leaks.
CFD Imports: Optimized Memory Management
for Large Datasets
Significant
Memory Savings: Optimizations have been implemented for models where
imported CFD records contain only heat transfer coefficient (h) and fluid
temperature (Tf) data, or only velocity (v) and fluid temperature (Tf)
data, as well as for models with unique time or vehicle speed values
across all records. Users can experience up to 60% memory savings when
opening, solving, or displaying imported CFD values in these cases.
Consistent
Performance for Complex Cases: Models with multiple records at the same
time value will maintain similar memory requirements as in previous
versions.

2025.1 while the magenta line reflects previous version.
Distributed Parallel Processing: Greater
Flexibility in Compute Environments
Expanded
MPI Library Support: Linux installations now
offer a wider range of MPI libraries, including Intel MPI versions 2021
and 2018, MPICH, and OpenMPI. Windows users can choose between Intel MPI
2021 and Microsoft MPI.
Simplified
MPI Configuration: You can now conveniently
set your preferred MPI library within the application preferences, in
addition to specifying it for command-line runs. This provides greater
flexibility and ease of use across different compute environments.
