Reply To: Problem on Material selection on FallingDrop2d
Hi Dan!
Just from looking at the code, in your case the material number 2 are the solid nodes as you are using the bounce back boundary. How are you taking into account solid-water interaction, as I cannot see any other post processor or something similar that you assign to material number 2?
And compared to the original example of FallingDrop2d, you are not assigning the material numbers 0 and 2 with the fields of MASS, CELL_TYPE and EPSILON, which could definitely cause problems with the implementation of the free surface model.
From my point of view, you could keep the original FallingDrop2d case and add a post processor on the boundary nodes to account for solid-water interaction.
Hope, this helps!
