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 hereÂ
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?
