When I first started running CFD back in the 90's, coarse grids and simplified combustion models were the norm, and for good reason – processor speeds were slow and simulations were mainly run in serial. Fast forward to 2013 and now we have a different story. Most commercial codes run in parallel...

The CFD mesh is one of the most discussed topics within the engineering community. It can be both problematic and time consuming – not to mention a source of numerous inaccuracies. There are different approaches to meshing but in this blog we are going to take a look at the cut-cell Cartesian...

Every CFD engineer in the world today has experienced the pain of meshing. The endless hours of trying to get a mesh to work with a particular complex geometry, trying to decide between structured and unstructured, deciding where to put mesh resolution, etc. With recent advancements meshing may be...
