Example 1

This video shows three-dimensional casting flow simulation (thermal fluid analysis) using particle method (Smoothed Particle Hydrodynamics, SPH method). The program is parallelaized using graphics processing unit (GPU). This video shows the actual calculation time (it shows the result in real time). The program calculates flow and heat conduction / heat transfer. Number of particles: 140,000 (fluid about 70,000, runner and cavity about 70,000).

Example 2

This video shows two visualization methods (cross section and isosurface) of particle simulation. The program is parallelaized using GPU. This video shows the actual calculation time.

Example 3

This video shows three-dimensional molten metal flow simulation in a die-casting runner (T shape) using the SPH method. This video shows the actual calculation time.

Example 4

This video shows three-dimensional molten metal flow simulation in a die-casting runner (V shape) using the SPH method. This video shows the actual calculation time.

Example 5

This video shows an example of interactive casting runner design. The designer can design the runner by deforming the runner shape while observing the change of the injection behavior from the gate of the molten metal. Free form deformation (FFD) is used for deformation. This video shows the actual calculation time. This program calculates flow and heat conduction / heat transfer. Number of particles: 840,000 (fluid: about 90,000, runner: about 750,000).

Example 6

This video shows another type of deformation. Various types of deformation are possible. In the latter half this video shows an example of changing the shape directly using a cylindrical deformation tool.
