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.

NVIDIA Turing Makes Real-Time Ray Tracing a Reality


Shaping up to be the biggest leap since the CUDA GPU back in 2006, Turing fuses real-time ray tracing, simulation, AI and rasterisation to fundamentally change how we look at computer graphics.

Featuring RT Cores to accelerate ray tracing, and Tensor Cores for AI inferencing, Turing pairs them together for the first time, making real-time ray tracing a reality. Turing changes the way content is created and enjoyed across a wide variety of industries, opening truly amazing creative possibilities today that were thought to be years away.

Real-time Ray Tracing Powered by Turing

RT Cores for Real-Time Ray Tracing

Armed with dedicated ray-tracing processors, named RT Cores, the computation of how light and sound travel in 3D environments is accelerated to up to 10 Giga Rays per second. Turing accelerates real-time ray tracing by 25x over the previous Pascal generation, and can be used for final frame rendering for film effects at more than 30x the speed of CPUs.

Tensor Cores for AI Acceleration

Providing up to 500 trillion Tensor operations per second, deep learning training and inferencing is accelerated by these Tensor Cores. This level of performance dramatically accelerates AI enhanced features such as denoising, resolution scaling and video re-timing.

New Streaming Multiprocessor

Raster performance over the previous Pascal generation is dramatically improved by the Turing architecture with an enhanced graphics pipeline and new programmable shading technologies. These technologies include variable-rate shading, texture-space shading, and multi-view rendering. All of this means improved VR experiences, and more fluid interactivity with large models and scenes.

CUDA for Simulation

Turing-based GPUs feature a new streaming multiprocessor (SM) architecture that supports up to 16 trillion floating point operations per second. Up to 4,608 CUDA cores with NVIDIA’s CUDA 10, FleX and PhysX SDKs mean developers can create complex simulations such as particles or fluid dynamics for scientific visualisation, virtual environments and special effects.


Currently, there is only speculation as to a release date. For now, the NVIDIA Quadro P4000, P5000 and P6000 are available at CAD Software Direct.


NVIDIA has enhanced its RTX development platform with new AI, ray tracing and simulation SDKs, to take full advantage of Turing’s capabilities. The result? Incredible designs, highly realistic simulations and stunning visual effects —faster than ever before. The NVIDIA RTX Server defines a new standard for on-demand rendering in the datacenter, enabling easy configuration of on-demand render nodes for batch and interactive rendering. It combines Quadro RTX GPUs with new Quadro Infinity software to deliver a powerful and flexible architecture to meet the demands of creative professionals. With industry leading content creation and render software pre-installed, the NVIDIA RTX Server provides a powerful and easy-to-deploy rendering solution that can scale from small installations to the largest data centers, at one quarter of the cost of CPU-only render farms.

NVIDIA Turing Optimised SDKs


With NVIDIA Turing GPU architecture at its foundation, the NVIDIA RTX development platform fuses ray tracing, deep learning, simulation, and advanced shading to fundamentally transform the creative process. Now, designers and artists can create amazing content in a completely new way with real-time, photorealistic rendering and AI-enhanced graphics, video, and image processing.


NVIDIA NGX is a new deep learning-based technology stack bringing AI-based features that accelerate and enhance graphics, photos imaging and video processing directly into applications. The NGX SDK provides pre-trained networks, making it easy for developers to integrate AI features.

GameWorks Ray Tracing SDK

The GameWorks Ray Tracing SDK enables ray-traced area shadows, ray-traced glossy reflections and ray-traced ambient occlusion. As part of the RTX platform, developers can create realistic, high-quality reflections that capture the scene around it and achieve physically accurate lighting and shadows.

Material Definition Language

The NVIDIA Material Definition Language (MDL) gives creatives the freedom to share physically based materials and lights between applications. Currently supported by applications including Allegorithmic Substance Designer, Chaos Group’s V-Ray, and the newly release Epic Unreal Studio 4.20, MDL SDK is now open source allowing for tighter application integrations.

Deep Learning SDK

CUDA 10 – Turing-optimized CUDA 10 includes performance optimized libraries, new programming model constructs for defining program execution, and enhanced graphics API interoperability. CUDA 10 will be releasing soon for use with Turing GPUs.

cuDNN 7.2.1 – The backbone for GPU accelerated frameworks, cuDNN 7.2 now features Tensor Core acceleration with FP32 inputs and outputs and more RNN use cases, including cell clipping and padding masks. Turing support coming soon.
