We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Also, I do not want to use this for high-volume fractions, I just want to assess the particle accumulation on flat surfaces using a DDPM approach, I know it's possible but I see the same error as shown above when I release particles from an inlet at a height 'h' made to fall on a flat surface.

I followed the method described here 
In a thesis titled 'CFD SIMULATION OF SEDIMENTATION OF SMALL PARTICLES' from Czech Technical University, details how we can get an accumulation of granular particles using DDPM. The problem arises when I change the particle inlet from the frontal 2D mesh surface (surface_body) to the top inlet of the rectangular 2D domain.

I keep getting a similar error as shown above, could you possibly help me understand why this could happen?
