Guys,
I refined my mesh using adaption option (> region adaption) but now cannot remove it. Why? I tried using the method mentioned in this post:


Coarsening mesh in Fluent

Coarsening works the same way as refinement but there isn't anything like an undo button. You cannot simply undo your refinement. You have to mark the cells using a register the same way to do the refinement/coarsening each time and it modifies the mesh each time.

Thank you Lucky,
but I don't know why coarsening doesn't work for me.
