DNS, LES, Or RANS Simulation For Your Next Automotive Design


The automotive industry is constantly advancing, with new innovations and developments emerging almost every day. The industry is committed to creating a more sustainable future with the growing trend towards electric-powered vehicles and mass production. In 2022, the global production of motor vehicles increased by 5.7%, producing 85.4 million vehicles. However, the industry faces the challe... » read more

Fuel Economy And Aerodynamics: The Yin And Yang Of Car Design


From the classic Model T to the iconic American muscle cars, the design of cars has been shaped by many factors over the years. Technological advancements, consumer preferences, and government regulations have all played their part. But one factor that has been a game changer is fuel efficiency. The Corporate Average Fuel Economy (CAFE) standards, introduced in the aftermath of the 1973 oil em... » read more

Understand The Physics Of Re-Entry Vehicles Using Numerical Modeling And Simulation


In the early years of space exploration, scientists and engineers dreamed of sending vehicles to Mars that could land on the planet's surface and explore its terrain. However, one of their biggest challenges was safely reentering the Martian atmosphere. Many early attempts at Mars missions failed because the vehicles either burned up during re-entry or crashed onto the surface. However, as tech... » read more

Cleaning Marine Geometries Has Never Been Easier


Ship designers and naval architects increasingly use computational fluid dynamics (CFD) tools for more accurate solutions, detailed physics, and quicker results. Marine ship design studies in the past relied mainly on scaled-down models in towing tanks for insights into ship resistance, seakeeping, propulsion, and maneuvering. However, these models had discrepancies in their Reynolds and Fro... » read more

Boost Your CFD Workflow Productivity With An API: Part 1


If you're in the field of computational fluid dynamics testing or studies, you already know how much time and effort it takes to complete the tasks involved. Hours upon hours are spent on geometry clean-up, meshing, and post-processing. Furthermore, when you're dealing with similar models that have new constraints or dimensions, the work can feel tedious. But don't worry! There’s a way to sim... » read more

Reduce Aquaculture Biological Footprint With Fluid-Structure Interaction Simulations


Aquaculture, which has existed since 1000 BCE, is gaining widespread recognition for its potential to provide sustainable fish products. This form of farming, also known as captive breeding, is the go-to method for fish farmers to satisfy the growing demand for seafood and freshwater fish. In aquaculture farming, choosing the right location is substantial for healthy breeding, such as having co... » read more

High-Fidelity CFD Mesh Generation With Voronoi Diagram


We are attuned to the fact that the law of nature, or nature’s rule, drives various scientific phenomena. Humans often replicate naturally occurring phenomena to achieve a desirable outcome, similar to how scientists mimic photosynthesis to generate energy. Comparable is the case with Voronoi geometries. These geometries are widely seen in beehives, the structure of sponges, rock fragmentati... » read more

Predicting Hull Resistance Curve Using Marine CFD


In this user case, Marintek uses Fidelity Fine/Marine and Hexpress for resistance curve prediction of a planning hull and its validation against the model test cases. Team involved End User: Eloïse Croonenborghs, Research Scientist at MARINTEK, Maritime division, Trondheim, Norway Team Expert: Sverre Anders Alterskjær, Research Scientist at MARINTEK, Maritime division, Trondheim, Norway... » read more

Easing The CFD Engineer’s Life With Automated Meshing


Mesh generation is where the user’s expertise and ingenuity can influence the convergence and accuracy of a computational fluid dynamics (CFD) solution by selecting mesh type, topology, and cell quality. But with the rush to automate mesh generation, will the control be ripped out of the user’s hand, or will a valuable engineering skill be lost? The extent to which meshing can be automated... » read more

Structured Grids Are Here For An Eternity


With unstructured meshes delivering promising results in resolving boundary layers, wakes, and other flow features for complex geometries, one might arrive at the conclusion that structured grids will soon be out of the markets because of their reputation for taking a long time for generation. On the contrary, structured grids give you two things that unstructured meshes may lack, i.e., quality... » read more
