Hi
I am running a spray injection simulation studying the evaporative cooling in a domain. The domain is 1.9m in length and 0.585m in width. The simulation is transient and parallel. I run the just the flow for the first 5 seconds and inject the droplets after 5 seconds. The simulation is running for 5second and throwing a error once the spray is initialized. For the inlet P = zero gradient and U = surface normal fixed value and for the outlet P= fixed value(100000) and U = pressure inlet-outlet velocity.

I am new to Openfoam I am getting ahold to an extent but could not understand the below error which I am usually facing in this simulation. Any guidance would be of great help.

I understand that there is a division by zero but not sure why this is happening.
