In our previous work, we have performed numerical simulation for the analysis of the vortex patterns on the postelectrolysis Pd rod and successfully obtained them within the rectangular domain using hydrodynamics for the incompressive fluid. In this work, we have improved the prototype calculation by using the following new concepts. Firstly, robust boundary condition was adopted. Secondly, cascade vortices were simulated by using combined vessels, where the fluid moved from one to the neighboring one. Finally, the vortex thread in 3D space was analyzed. As a result, the flow pattern from one vessel to neighboring one was obtained. This will contribute to know the physical properties of the hypothetical particles mass relating to the CF anomaly, e.g. high/low energy process, traces of local energy deposition and so on.
