Class 3 Error
If the Schmehl secondary break-up model is used without the viscosity for the droplet material being set, then the droplets will break up to the minimum allowable droplet diameter. This is incorrect and may not be noticeable.
This is due to the solver not checking whether the viscosity is set, and then using a non-physical zero value when it
Ensure the viscosity is set.
