While a large contingent of Fidelity CFD team members are at the AIAA SciTech Forum this week, let's take a look back at what happened here last week. This post's featured image is a blast from the past of flow through a valve. (Image created in FieldView…

Fidelity Pointwise generates two-dimensional (2D) and three-dimensional (3D) grids that are crucial for most of the computer-aided engineering (CAE) analysis process. Grids are exported to an analysis software to simulate a design; therefore, the grid and…

While using Fidelity Pointwise, there are two approaches to handling dirty and complex geometries. The first approach is fault tolerant meshing, while the second newer approach is solid meshing. The latter new technique creates models and quilts while…

The Marine CFD field is evolving, and requirements are increasing: more applications, more physics, more accuracy, and always faster workflows. The complexity of geometries…

Traditionally, adding cells to a mesh, known as H-refinement, was the primary means by which solution accuracy could be improved. The additional resolution enables the capturing of flow phenomena often diffused by coarser variations of the same mesh.…

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 thrust without…

Our partners at neptech have published a new CFD case study of modeling the flow in a Y-Pipe. Here's their introduction.

Y-Pipe structures are widely used in many manufacturing and research areas for mixing different reactant solutions. The flow…

Norman F. Foster, Jim G. Coder, and Warren J. Baker from the Applied Research Laboratory and Department of Aerospace Engineering at The Pennsylvania State University used overset meshes to simulate rotor-hub vortex shedding in helicopters using Fidelity…

In CFD history, structured meshes came first, and they are still in use today. Structured meshes offer several main advantages, such as precision, speed of generation, and uniform distribution…

Let's take one last look during 2022 of what's happening here at Fidelity CFD.
