Reply To: Modeling the interface in overlapping fluid zones, dynamic mesh problem

Hi,

You are encountering issues with overlapping geometry or shadow walls, it might be due to how the geometry was created or imported. Consider revisiting the geometry creation process or importing the geometry in a different format to see if it resolves the issue.

Negative cell volume issues often arise when using dynamic mesh, especially if the mesh is being deformed too aggressively or if the mesh quality is poor. Adjust the dynamic mesh settings in Fluent to control the deformation more effectively.
