Is It Always The Mesh? Part 3: Non-Orthogonality
Quite often I hear complaints about the required number of non-orthogonality correctors to achieve convergence, and how it’s worthless even trying to run a solver on a mesh, etc. The point of this series of posts is to give you an overview of the popular myths and to...
2D Geometry and Case Preparation of a CHT Simulation
In this report, we will show the case preparation for a CHT simulation. Geometry preparation The model of the battery pack was given as a 2D drawing in a DXF file format - a vector format mostly used by engineers and architects for 2D drawings during product design....
How Engineers From In silico Achieve Accurate And High-Quality Meshing Results
by Dr. Rober Keser I have been using cfMesh for more than seven years now, and it has had a tremendous impact on my CFD workflow from the very beginning. I started using the open-source cfMesh for grid creation for various assignments during my master’s degree, and I...
Vertical Axis Wind Turbine and Rotating Mesh
This case study demonstrates how to mesh and set up a multi-domain case with a rotating mesh. The analyzed geometry represents a Darrieus-Savonius wind turbine. Geometry preparation For more detailed tips and tricks on how to prepare your geometry and provide...
Is It Always The Mesh? Part 2: Skewness
Quite often I hear complaints about skewness, and how it’s worthless even trying to run a solver on a mesh etc. The point of this series of posts is to give you an overview of the popular myths and to help you understand what’s going on in your Finite-Volume CFD code...
