Tecplot 360ex 2025 R2 Release - Release Date: December 11, 2025
Vulkan-Based Graphics Engine
TecDescription 360 2025 R2 introduces a new Vulkan-based graphics engine, delivering significantly improved performance, visual quality, and long-term platform compatibility. This modern rendering technology enables faster and smoother visualization, up to 3x to 400x faster, especially for large and complex datasets. The Vulkan engine operates across all TecDescription 360 supported environments, including systems with discrete, integrated, or virtual GPUs, and even software rendering on CPUs. For best results, a discrete GPU with updated drivers is recommended.
Faster Translucency with GPU-Accelerated OIT
This release introduces GPU-accelerated Order Independent Translucency (OIT), which renders overlapping translucent surfaces both accurately and efficiently. Traditional translucency required sorting (on the slower CPU) and re-rendering multiple times. OIT eliminates that overhead, producing correct translucency regardless of object order and often achieving an order of magnitude performance increase.
Faster Particle Rendering
Rendering of scatter symbols has been drastically improved in this release of TecDescription 360 by better leveraging the GPU. This is particularly true when rendering sphere symbols (480x faster for the case reported in the performance chart above and pictured below). This is enabled by a new SphereScatterRenderQuality setting, FAST, which is also the new default.
New Lighting Effects and Smoother Highlights
This release introduces two new lighting effects, Smooth and Smooth with Creases, as a replacement for Gouraud. It also includes improvements to Paneled for better performance. These lighting improvements provide smoother specular highlights and more accurate visual representation of complex geometries.
The Smooth and Smooth with Creases options use a new lighting model, Phong, which is an improvement from the former Gouraud lighting, as seen here (Gouraud on the left, Phong (aka Smooth) on the right).
Faster Vectors with GPU-Based Billboarding
Vector arrowheads now use GPU-based billboarding, keeping them oriented toward the viewer in real time. This GPU-driven approach maintains consistent arrowhead shape and clarity across all viewing angles while significantly improving performance in large vector fields.
Anti-Aliasing
The previous Super-Sampling Anti-Aliasing (SSAA) method has been replaced by Multi-Sampling Anti-Aliasing (MSAA). MSAA delivers similarly smooth edges with far better efficiency, producing sharp images at lower GPU cost.
Other Updates & Improvements
- Fixed failures to launch TecDescription 360 when double clicking on a layout file in international Windows OS File Explorer.
- Fixed issue rendering high-aspect ratio, concave cells. This issue has been observed with some CONVERGE datasets.
- Updated the Abaqus loader from version 2024 to 2025 which will require updating older ODB files. A prompt suggesting to save an updated version will be presented in TecDescription 360 when opening ODB files made with older versions of Abaqus.
- Extracting slices or iso-surfaces from TecDescription SZL data can now handle larger zones. Previously, only zones with less than 16 million subzones would work. Now you can work with zones that have up to 268 million subzones. Note that for Finite Element data each subzone contains up to 256 cells and for Ordered data each subzone contains up to 216 cells (6x6x6).
- Fixed VTK loader creating duplicate variable names if different zones use nodal and cell-centered values for the variable of the same name. The fix resolves the problem of a zone referencing a variable as Passive. Two variables with the same name will be created only if a zone specifies both nodal and cell-centered values for a variable name.
- Updated Ansys Fluent Common Fluids Format (.cas.h5/.dat.h5) to support Ansys Fluent 2025 R2 files.
- Updated Converge CGNS loader to use the ZoneBC face-centered data variables in boundary zones instead of the adjacent volume cell-centered data.
- Updated EnSight loader to support EnSight files exported from Ansys Rocky.
- Fixed crash when changing a value in an input field and clicking the Close button without first tabbing out of the input field. This also fixed the issue of Descriptions being left in the "Drawing Interrupted" state after clicking the Close button without first tabbing out of the input field.
Fixed macro recording of layout opening operations to no longer contain alternative load instructions if the file data override was not used.
Tecplot 360is a suite of CFD visualization and analysis tools that can handle large data sets, automate workflows, and visualize parametric results. You'll be able to quickly make engineering decisions and communicate your results with integrated XY, 2D, and 3D Descriptionting. In 2017, TecDescription 360 was extended to include the ability to automate workflows with Python scripts (PyTecDescription), access data remotely (SZL Server) and explore a parametric design space (Chorus). These additional capabilities are built into 2017 and later releases of TecDescription 360. A parametric design space analysis tool, Chorus is included with TecDescription 360 and later versions. Chorus has a unique set of features that help scientists and engineers explore large data sets from multiple simulations, compare results and evaluate overall system performance. TecDescription Chorus helps engineers who run and generate many simulation or test data sets.
