S-version finite element method (S-FEM) is an evaluation method for fully automatic crack growth simulation system on the basis of auto-mesh technique. S-FEM has been applied to simulate the crack growth considering the material boundary. Crack growth analyses have been conducted for a plate consisted of two different materials by tensile membrane stress and a stainless steel piping under weld residual stress field. Effects of the crack growth rates in the different materials on the behavior of the crack growth have been evaluated by S-FEM and the influence function method. Results show that the crack sizes obtained from each method are in a good agreement.

Client/Server visualization is important technique to analyze simulation results on remote supercomputer. However increasing of data size and complexity reduces the processing speed on Server. Our proposed Client/Server visualization system using Particle-Based Volume rendering can provide high performance for generation of visualization primitives (particle data) by Monte-Carlo simulation on Server. The particle data which transferred to Client is relatively small size compared to the original data because its size is determined by screen resolution. Using supercomputer BX900, we processed unstructured volume data with 
100 million cells in seconds.
