Are Structured Methods Still The Workhorse?
Posted Thu February 28, 2002 @07:21PM
Print version Email story Tweet story
Structured Unstructured solvers have been around for some time now (even commercially), but how many people are using them for large-scale production CFD work?

Structured grid generation is admittedly cumbersome and time consuming, however, the time spent optimizing the mesh is well rewarded.

The best structured solvers are faster, more accurate, more robust, and use less memory than the best unstructured codes. Also, because structured codes have been around for so long, they tend to have the most physical models.

Furthermore, post-processing tasks are far easier on structured grids. Topological planes within the grid are ideal locations for generating qualitative plots and calculating quantitative values such as mass flow.
