Particle-i was not found in Partlicle-j array
I'm working on a simulation of circular pipe flow. When I used the artificial viscosity, the result looks good. When I worked with laminar viscosity+SPS (only this viscosity option was changed, others stayed same), the execution of tool PartVtk4 was aborted, because " Particle-i was not found in Partlicle-j array."
Does anyone have an idea what's the problem?
Thanks a lot for the help.
