Reply To: Something about settlingCube3D
there could be several reasons. By the cuboid size do you mean the settling cube or the domain. If it is the particle, it would be larger than the domain. If it is the domain size, according to the resolution that would be more than 500.000.000 cells. Depending on the machine you are using maybe the RAM is not enough, this would lead to the process being killed during geometry creation.
On the other hand, are you already using STLs? In this case the STL file should be watertigth to be sure.
Do you get some kind of error message?
