I've encountered a strange problem when running a simple dam break case. After I've created the initial states and boundary and run the simulation, at time t = 0 s there are additional particles created at a random area inside the domain.
It doesn't really interfere with the simulation since the particles drop down and disappear at t = 1 s, but it is a computational strain since more memory is needed at the beginning.
In the image, the extra particles can be seen to the left of the problem domain. Does anybody know how could this be fixed?
Thanks and regards.
