The development of scientific software applications that can assist in and accelerate the process is bringing a new dynamic, helping to bring down costs while reducing the risk of failure of a drug or device. Simulation software provides a new means of testing any prototype healthcare device, and is becoming increasingly important in biomechanical research and is commonly referred to as in silico testing, referring to the silicon chips that are integral to any computer. Software vendors such as Ansys have collaborated in integrating their software in healthcare modelling and simulation, assisting in breakthroughs in healthcare device development.
Where Ansys is leading currently, its competitors will surely follow suit. In a few years time, it is likely that specialized and rare CAE software will no longer be used by only a handful of finite element specialists, but by resources across the organization. Managing software such as the Ansys Workbench is just as easy as managing Autodesk products with OpenLM, as well as the GPUs required for the necessary processing power. One of our consultants can advise you on your unique situation.

Just recently, an NVIDIA partner, Resolved Analytics, published a survey on CFD users and tools. One of the statistics shown is the commonly-used levels of parallelism by CFD users today. In CFD, parallel execution refers to dividing the domain or grid into sub-grids and assigning a processing unit to each sub-grid. At each numerical iteration, the sub-grids communicate boundary information with the adjacent sub-grids and the CFD solution advances toward convergence.
Figure 2 shows the performance of the first release of Simcenter STAR-CCM+ 2022.1 against commonly available CPU-only servers. For the tested benchmark, an NVIDIA GPU-equipped server delivers results almost 20x faster than over 100 cores of CPU.
GPU-accelerated runs are delivering consistent results compared to CPU-only runs, and Siemens delivered a product that can be seamlessly moved from CPUs to GPUs to get the results faster and effortlessly. The result is that you can now run simulations on-premises or on the cloud, as A100 GPU instances are available from all the major cloud service providers.
Siemens showed similar results in their announcement of GPU support in version 2022.1 when comparing CPU-only servers on-premises and in the cloud for both previous-generation V100 GPUs and current generation A100 GPUs. They also showed the performance of a large, industrial-scale model and the equivalent number of CPU cores required to get similar run times as that of a single node with eight GPUs on it.
The performance of the Ansys Fluent 2022 beta1 server compared to CPU-only servers shows that Intel Xeon, AMD Rome, and AMD Milan had 1.1x speedups compared to the NVIDIA A100 PCIe 80GB, which had speedups from 5.2x (one GPU) to an impressive 33x (eight GPUs).
The Ansys Fluent numbers drove some major excitement. They showed that a single GPU accelerated server for their selected benchmark and associated physics could deliver nearly 33x the performance of the standard Intel processor-only servers common today.
Such fast turnaround times are due to GPU acceleration of the two most used commercial CFD applications. This means that design engineers can not only incorporate simulations earlier into their design cycles but also explore several design iterations within a single day. They can make informed decisions about product performance quickly instead of having to wait for weeks.
The most recent Supercomputing Conference featured research by a team that studied algorithmic changes which produce reductions in floating-point atomic updates required by large-scale parallel GPU computing environments. The runtime of several kernels is dominated by the update speeds, and therefore efficiencies found in this area have the potential for large benefits. Also, though FUN3D is a NASA and United States government-only tool, the discussion in this paper has applicability to other unstructured Reynolds-averaged Navier-Stokes CFD tools.
Stationary cracks provide an instantaneous view of the state of a crack in the structure. The engineer can only know one thing from this type of analysis: will the crack grow or not. No insight is provided into the second and third of the common questions asked in the previous section. Simple closed-form solutions are available for engineers to estimate the integrity of a cracked structure, and these can be found in literature reviews and textbooks. Many closed-form solutions take the resulting stress field caused by loading, the current crack length, and an empirically determined factor to determine stress intensity. A few examples are shown here, for plate geometry of varying sizes.
The first step in a one-way coupled model like this is to setup and solve the CFD model. This particular application has a low particulate loading, so one-way coupling is appropriate. The setup of this particular model included specification of the air knife and suction outlet flowrates, while specifying pressure boundaries for the clean outlet and compost inlet. Once solved, the developed flow field will be exported to Rocky using the Rocky Export tab at the top of the Fluent interface. Note that the Rocky Export tab is only available after installation of Rocky along with the Rocky coupling module. To perform a one-way export, first select Rocky Export, then Export one way data, and finally export current data to Rocky.
Finally, your model is ready to solve like normal. All of the typical postprocessing results you can expect from Rocky are still available to you, only now particles can be affected by the imported airflow. The workflow demonstrated here works well for transient or transient periodic one-way coupling as well. Two-way coupling does not rely on the Rocky Export tab in Fluent. Instead, Rocky will launch Fluent itself once provided the appropriate Case and Data files to start from.
While this article explains the setup of a bucket elevator, expressions are quite valuable for other Rocky simulations as well. When calculation is needed to convert between a key value and the inputs needed to implement that change in Rocky, expressions and aid in accuracy and speed of running multiple test cases. For this example, it is trivial to run the model at different head pulley speeds as only the PulleyRPM variable needs to be modified.
Software simulation allows for rapid testing and iterations as many changes can be made virtually with a few clicks. This allows for quick changes and adjustments without the need to rebuild physical models. The flexibility to develop multiple iterations saves both time and resources. In contrast, physical prototyping may require more time and resources through each iteration. While physical prototyping for real-world testing is a crucial phase in product development, ideally it would be limited due to the time and costs involved. In addition, during real-world testing, unexpected issues or challenges can arise that are native only to the test environment.
If you wanted to write a GPU ray tracer a few years ago, you had two options: Either use OptiX, or write your own in CUDA. Today, you not only have much faster ray tracing thanks to hardware accelerated ray tracing, you also have more choice in the sense that you could also use DirectX Ray Tracing, or Vulkan Ray Tracing extensions. With all this choice, the question is why one would need anything more than that.
After successfully importing the geometry, we will move on to adding the local sizing. You only need to go through this step if there are faces or areas where your mesh needs to be finer, or you need to capture more gradients. Once done, you will see the green check next to it.
We tweaked our modeling engine and are happy to report that we have improved general compute performance of mid to heavy-weight modeling commands. For example, performing a complex 5050 model patterning task was initially tested to take around 15 minutes to compute. Now it only takes 3 minutes.
The process of placing components on the PCB in the correct pattern is critical when laying out a circuit board closely followed by routing your signals. Both these processes are dependent on the grid being used on PCB. Commonly there will be two grids setup: one of them will be viewable, while the second grid is referred to as the alternate grid.
An outcome from generative design is only as good as its setup when it comes to truly meeting your design needs. In this update, we are adding the ability to simulate the loads associated with additional components attached to the item that you are generatively designing, without having to understand the forces that may occur at the interface of the connection. The manual point mass command will allow you to apply the mass of the attached components through the connection points to simulate the associated load. Being part of the Experimental Generative Solvers and Features preview, a manual point mass can be used in conjunction with other preview features like remote forces and constraints, symmetry planes and model, displacement or buckling limits.
Previously only available in the 2D Contour milling toolpath, you now have the option to specify a Finishing Overlap distance for your 2D Profile toolpaths as well. This will help improve the consistency of the cut when manufacturing components with Laser, Plasma or Waterjet machines. Taking advantage of Finishing Overlap will enable you to create cleaner cuts by avoiding the lead in and lead out occurring at the same point. It can also eliminate secondary deburring/grinding operations downstream, reducing manufacturing costs.
