I did a 3D transient particle tracking from a 3D transient flow simulation. When I export/disply the result. I notice there is a big gap in particle path for every particle. I ran for 30 years. There is a time gap of more than 5 years. I asked WASY support about it. The response suggests it has to do with element size or pumping well. There is no pumping well in the area where the gap occurs in my model. I want to see particle path with smaller time step so that I can display the result to clients. With current result, the result leads to more doubt.

Are there users having similar problem? I would like to know how you resolve the problem.

Thanks
Jason
