Fluid Flow
Analysis
Shown in Figure 1 is the CAD data of an Aluminum-Die Cast
part for cell phones.

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.
