I am trying to fill a container from an "inflow" inside the container, making the liquid rise and overflow.
Obviously any source that is submerged will stop emitting. I could of course add a pipe and let the liquid flow in from another container but I was hoping there is another more elegant solution, like constantly emitting particles inside the fluid.

Any advice welcome.
Thanks in advance.

You can introduce divergence into the simulation, either through a point attribute on the FLIP points or by sourcing a divergence field from SOPs with a positive value. Positive values will force the volume to expand around the affected areas.

Thank you that helps a lot. Never thought of divergence in that context.
