Default Limit sub-steps in Lagrangian unsteady simulation

taillanm is on a distinguished road

I am simulating a gas jet impinging water (fluid film, lagrangian multiphase, multi-component gas, multiphase interaction).

I started with a small time step (1e-5s) and started to increase it to 2.5e-5s, then 5e-5s. I realize that the amount of lagrangian sub-steps per time step increases massively when I increase my time step thus slowing down my simulation.

Is there a way of reducing the substepping?
