How to preserve edge grading of blocks during rotation?
 

Hello,

I have an axisymmetric model for which I am generating 2D blocks and specifying the edge gradings in ICEM.

I am converting these 2D blocks to 3D by rotating them through the dedicated option of Create Block> 2D to 3D> Rotation. The major problem with this is that the edge gradings and linked edges that I have generated in 2D are not carried over to 3D. This is creating an issue because now, I have to re-link and re-grade the edges for the rotate 3D model. This is extremely time consuming.

I specifically went with the rotation approach because of the following reasons:
1)grading in 3D is really complicated for my setup as it has many blocks.
2) i want to merge an Ogrid topology with these rotated blocks because there is no direct way we can generate O Grid in a quarter-3D model.
3) I am limited by the number of processors ICEM can use so it also limits my iterative process of mesh generation


I posted this issue in ANSYS Learning Forum but did not get any satisfactory reply from them.
