Nesting boundary

#1 Unread post by Renato_Cecilio »

Hello.
I am having an issue with my nested grid boundaries.
When I set DT in the child as a multiple of the parent (Refined Scale) an offset develops in the free surface at the child boundaries.
Like 300s in the parent and 60s in the child grid.
However, when they are both identical to the child grid the offset disappears.
Any ideas?
