Computational Fluid Dynamics Blogs

Most engineers are of the view that all mesh generators use an underlying geometry that is discrete in nature, but in fact, Fidelity Pointwise can import and mesh both analytic and discrete geometry. There are several pros and cons to using both analytic and discrete geometries.

Good Monday to you all. There are only 96 days left in 2022, and hopefully, our activities at Fidelity CFD can help you make the most of them. From the Blogs I like to say that geometry models are to mesh generation what turbulence models are to CFD....

Happy Monday! ICYMI, here's a summary of what happened last week at Fidelity CFD. From The Blogs Construct Unstructured Block Assembly with Fidelity Pointwise - There are many ways to create an unstructured volume mesh in Pointwise. One of them ...

Mesh generation in computational fluid dynamics must achieve a balance between solution accuracy and simulation convergence time, and this is possible by controlling the local element size gradation in unstructured meshes

Still today cavitation is one of the most challenging topics that CFD engineers have to face. This blog article summarizes some state-of-the-art CFD technology for cavitation prediction, covering different applications and CFD features to answer engineers' needs.

With Fidelity Pointwise, one can skin a block, manually or automatically, using structured or unstructured block assembly. Learn when to use manual or automatic block assembly from this blog article.

Fidelity Pointwise includes the concept of meshing regions defined on the CAD level, known as quilts. Quilts provide a watertight representation of the geometry that hides unnecessary complex topology in the underlying geometry and reduces the meshing regions.

Why Unsteadiness Is Important in Turbomachinery and How to Model It Owing to its high complexity, unsteady flow in turbomachinery often generates high levels of noise, low efficiency, vibrations, and increased fuel consumption. Those are the most typ...

Witness the next generation of meshing for marine applications: Mesh any geometry at the highest level of accuracy and speed, guaranteed. In this 30-minute webinar we present various new meshing features that will accelerate your workflow at all levels, from CAD preparation to mesh analysis, creating a solid basis for high-accuracy CFD simulation.

Structured grids offer two things that unstructured meshes may lack, i.e., quality and control; and since the choice of grid plays a significant role in the accuracy of the solution, it is evident that the structured grids are here to stay!

Recently, I had an opportunity to interview another woman working in CFD, Virginie Barbieux, Senior CFD Product Engineering Manager at Cadence, to learn a little about her, her career journey to date, and a few pieces of advice that would benefit other women engineers or practitioners in CFD.

Questions I get asked a lot include "Are you nuts?" and "What exactly do you do all day anyway besides surf the interwebs?" A third is "Are you hiring for the Fidelity CFD team at Cadence?" Search the Careers Webpa...

For the given 5 geometry configurations, with Fidelity Pointwise high-order meshing, linear meshes are curved and require fewer elements to accurately represent curved geometry and capture complex flow features.

Virtual reality in CFD, especially for post-processing the simulation results, can help users interact with the model to study the physics and find ways to improvise the design.

The 10 steps mentioned in this article can ease the preprocessing step (primarily importing CAD files and meshing) for a CFD solution using the Fidelity Pointwise meshing tool.

The shift left approach is slowly being realized and employed in the marine industry to reduce the time to market, and hence, there is widespread use of CFD tools for the early prediction of faults in the ship design cycle.

Towing a ship model into a humongous basin of water allows naval architects to identify and understand the different factors that contribute to the seakeeping, maneuvering, and icebreaking capabilities of the ship.

The GPPS 2nd Turbomachinery CFD workshop, co-organized by Cadence, will take place as part of the GPPS Chania22 conference, on September 11, 2022. This workshop aims to evaluate and improve users’ trust in RANS turbomachinery solvers by conducting a validation and verification (V&V) study on two cases: the TUDA-GLR-OpenStage transonic axial compressor and the BUAA low speed large scale axial compressor-Stage B.

Advanced control and calibration units, process simulation technologies, and 1-D and 3-D CFD simulation tools can help design and control a component or an entire processing unit for optimum plant performance, plummeting any chances of a disaster.

After a very successful first CadenceLIVE 2022 edition in Silicon Valley last month, CadenceLIVE has started it's world tour! The CFD Track specifically will be coming to Boston on September 14th and Munich, Germany on November 21-22. The call for presentations is open.

Let me get this out of the way right up front. Next week's International Conference on CFD (ICCFD) is being held in Hawaii, at the Royal Lahaina Resort on the island of Maui. It's a tough job, but someone's got to do it. It's been 36 ...

SMM, the leading international maritime trade fair, is back. The world of shipbuilders, naval architects, offshore experts and maritime suppliers will be gathering in Hamburg, Germany. Our partner NUMECA Ingenieurbüro is offering a full-day workshop dedicated to maritime CFD solutions on September 8th. Register here!

Our Cadence Channel Partner in Scandinavia, neptech , shares a case study investigating the interaction of a coaxial rotor system and how to optimize its efficiency. Coaxial rotor systems are appealing for multirotor drones, as they increase th...

Throughout this season at Formula One, porpoising has been the most talked-about phenomenon. To remedy porpoising, FIA has issued new directives, and whether these new directives will be helpful or not is yet to be witnessed.
