Question about Y grid
 
Hi,

When I use Y-grid generation button, why there's erro message 'number of degenerate corners!=2'? What does it mean and how to fix it?:confused: (I use ICEM.)

Best regards and many thanks,
lnk

did you merge before ? i get that when my block is not a triangular shape

Exactly if you are trying to convert a block which is not in triangular shape then you will get this error. First merge the vertices by any of the methods i.e Merge vertices directly or using a Collapse block method and then convert the block into Y-block.

reassociate edges on the blade again. I guess it is some bug that after creating Y-block, associations get reset.

Delete all the association and do all the associations again.
