Reply To: Something about settlingCube3D
if you want to use STL files you will have to create a new SmoothIndicator. I wanted to suggest to have a look at the other indicators and use them as a blueprint in the process of creating this new indicator.
Similar, if you want to combine some simple shapes, this will also require some programming and modification of some SmoothIndicators.
Or you can maybe simply you case to an object that can be described by an analytical equation.
As you described, you want the particle to float between the two phases. Setting the acceleration / force could be non-trivial as this force is currently just a global parameter. Therefore the current code might not be able to correctly depict an object’s buoyancy forces.
