Skewness & Decomposition
Hi,
Unknowingly, I've been running simulations where a low number of elements in a VERY complicated flow region have very high skewness. Unfortunately, I only realized this well into processing my simulations. I have since attempted to replace the very tight corners which were causing the skewness. However, this has made it practically impossible to make use of a rectilinear mesh. Aside from changing the geometry, are there other approaches that can be used to fix skewness? Thanks in advance. |
Re: Skewness & Decomposition
If you are using Fluent 6.3, trying making polyhedra from the skewed cells to reduce the skewness. This helps most of the time.

Re: Skewness & Decomposition
Not sure I completely understand. Should I redesign the entire face that's a problem? I am unfamiliar with how to manipulate the actual cells (aside from very cumbersome methods) in the way you mention.
Thanks for the help so far. |
