| Summary | 0000457: adding double grading feature to blockMesh | ||||
| Description | I just want to recommend that a double directional edge grading in blockMesh would be fine. This way it's not necessary to create a lot of blocks. | ||||

Clearly there is a need for better control of grading in a block and a separation between block topology and the organisation of the cells in the blocks. However the double directional grading proposal is a very specific and limited way of addressing this need and the use of a negative expansion ratio parameter is a bit clunky. I have implemented an alternative and much more general strategy which covers the particular case of double directional grading as well as offering grading in any number of block sub-sections with grading specified per section.
