Altair Accelerates Engineering Simulations with NVIDIA GPUs

Nvidia GPUs with Altair

Whether analysing fluid dynamics or performance, engineers need to create high-quality simulations long before a physical prototype takes shape.

To help engineers gain deeper insights into their designs, Altair AcuSolve and Thea Render — now offer enhanced support for NVIDIA GPUs, which produce incredible performance and speedups.

AcuSolve Enhances CAE Workflows

AcuSolve is a general-purpose CFD software that helps engineers simulate the fluid flow with turbulence and heat transfer of a design. With NVIDIA GPUs, AcuSolve users can perform simulations up to 4x faster than on CPU only configuration.

With RTX Server powering Altair users can design new models faster and more efficiently

Thea Render Brings Design to Life

Thea Render, a powerful 3D rendering and animation tool, enables engineers to visualise realistic previews of their work, and the CUDA-based renderer can now deliver ray tracing with the NVIDIA OptiX AI-accelerated denoiser. In addition, Altair Inspire Studio leverages GPU-accelerated AI to reduce the time it takes to render high-quality, noiseless images.

Altair applications use CUDA, the parallel computing and programming platform featured on NVIDIA GPUs, to gain significant increases in speed and throughput. This lets engineers freely and quickly explore designs and make decisions based on more accurate results.

RTX Server Accelerates Computations

In addition to GPU support, Altair announced NVIDIA RTX Server validation of Altair ultraFluidX, an aerodynamics CFD software, as well as Altair nanoFluidX, a particle-based CFD software.

With RTX Server powering Altair ultraFluidX and nanoFluidX, users can design new models faster and more efficiently during the day on NVIDIA Quadro virtual workstations. The same RTX Server can then be used to complete large-scale CFD simulations overnight instead of taking days to compute the data.

When engineers arrive the next morning, the simulations are ready for them to analyse. This allows teams to understand the performance, behaviour and mechanics of their models earlier in the design process — all while using a more energy-efficient computing system that’s accessible on premises or in the cloud.

Altair software and NVIDIA GPUs are available now at CAD Software Direct

Thea Render 2.0 for Sketchup Available Now

Thea Render for Sketchup 2.0

Thea for SketchUp is a state-of-the-art Biased, Unbiased and GPU renderer with a rich set of innovative features, a powerful material system and its own advanced studio, all-in-one. Thea Render comes with high quality materials, resources exclusively for licensed users, integration with various modelers, a robust SDK and advanced features such as Photometric Analysis, Colimo Support and many more.

The plugin is a fully integrated rendering environment that enables photorealistic and physically accurate renderings to be easily created directly inside SketchUp, eliminating the hassle of importing and exporting models. With a completely redesigned user interface and accessibility to multiple rendering engines, creating renderings with the appropriate look and feel is intuitive and efficient. And with CPU as well as GPU support, Thea runs effectively on any hardware configuration.

Offering the ultimate experience in usability and exceptional functionality, Thea Render 2.0 for SketchUp provides many new features including:

    • New user interface
    • On-line material library
    • Denoiser
    • Tone Mapping
    • Fog Medium

Section Cuts (New)
Section Cuts are now supported from SketchUp 2014 (up to the latest version). Section Cuts allow you to cut through buildings and rooms leaving the interior lighting the same, as the external walls would be still in place.

Interactive Render Overlay
Thea for SketchUp allows you to run an interactive render either inside Thea, or directly inside SketchUp view – a feature called Interactive Render Overlay. Additionally, with the use of Interactive Region Rendering, a desired part of the SketchUp view can be selected rendered providing ultra fast feedback for complex scenery. It is a valuable in the workflow as it gives you an immediate visualization of geometry modifications, environment, depth of field, reflections, light distribution, material properties and external Thea models in a scene.

External Models
High quality external Thea models can be inserted as an empty wireframe box. In a rendered image, they will be translated into very detailed originals. This allows an easy population of your model with impressive looking trees, grass, cars and detailed furniture. There are already a few libraries of render-ready objects.

Materials
Thea libraries can be found inside SketchUp Paint Bucket (in SketchUp Material format) and inside Content Browser for applying Thea materials easily and directly! The “Convert Thea Material(s) to SKM” tool helps you convert your own libraries. Licensed users can download additional libraries, in both Thea format and SketchUp materials format. You can even choose one of the available Thea material presets (they also come with useful parameters that let you adjust their properties).

Export to Studio
It is possible to export the scene to Thea Standalone Studio and take advantage of additional staging tools. Using the 64-bit Studio (currently available on Windows / Linux), you can render heavy scenery in very high resolutions without RAM limitations.

Animation
Thea for SketchUp is able to render animations as they are visible in the SketchUp view. All animation plugins that show their output directly in the SketchUp window, while a built-in scene animation is being played, are supported.

Channel
Many SketchUp users possess exceptional post-processing skills. Thea for SketchUp allows rendering a model with multiple images containing separate channels, popularly called “passes”. Those channels may include, for example, shadow, depth, direct light, transparency and reflection information. Combining them in an artistic way gives full control over the final image and lets you create otherwise hard-to-achieve effects.

Panoramic Images
You can render a model using a camera with spherical projection. The resulting image will be a panorama that can by viewed by an external program or a web application. It is especially useful for presenting interiors to clients as it gives an excellent impression of a proposed solution.
