Hello loics,

Some times left handed faces create some negative volume cellsĀ 
To overcome this problem try:
1. Reverse the order in which the surfaces are picked inside the Grid Interfaces panel while creating the non-conformal interface if there is non conformal interface
2. Try the TUI command /mesh/repair-improve/repair (with /mesh/repair-improve/repair-face-handedness yes)
3. If that doesn't work, look carefully at the two surfaces involved especially at corners and turns. Modify the mesh to make sure that the two surfaces are not passing through each other at any point.

4. finally check the dynamic mesh settings.

This should help you solve the problem.
