We performed an element analysis corresponding to the above mentioned part with a finite difference mesh in order to conduct the fluid flow analysis. An analysis model for the fluid flow was created exclusively for the Die Cast/pre-processor solidification simulation of the part. The analysis model was modeled from the runner section to the product section. Divided 547 ways in the X direction, 251 ways in the Y direction, and 78 ways in the Z direction with one edge of 0.255mm. All together it made a 10,709,166 element mesh. It required about two minutes to divide on a pre-processor. Shown in Figure 2 is the analysis model of the mesh generation. The speed of the flow was set to be 10m/sec. at the inlet.
Shown below is the software and hardware environment that was used in the analysis.

A fluid flow analysis was conducted considering the above mentioned analysis model conditions.
Indicated in Table1 is the required analysis time and memory that was used for the fluid flow analysis.
