Hello Bushrat,
The error you're encountering with the larger agitator in Ansys Discovery might be related to the setup of the rotating fluid zone and its interaction with the gravity settings.
Given that the smaller agitators are working fine, it's possible that the size of the larger agitator is affecting the alignment with gravity due to the way the rotating fluid zone is defined or the mesh is generated around it. It's important to review the setup of the rotating fluid zone for the larger agitator, ensuring that the volume and mesh accurately represent the impeller's dimensions and that the boundary conditions are correctly applied.
Refer this In-Depth - Fluids - Ansys Knowledge and Rotating Fluid Zones tutorial for more information.
Let me know if further assistance is needed.
Regards,
Devendra
