Abstract

Abstract:

Developing the user-friendly cloud platform for high-performance numerical software deployment has great engineering significance. Based on the high performance computing resource of Web industry cloud platform, the large-scale high performance test on the domestic ship hydrodynamics numerical software is carried out. Selecting a typical Knock Nevis KCS model with a bulbous bow, through the parallel solver of the software, the wave-making problem of a real ship is simulated, in which the wave shape near the actual ship hull is basically consistent with that of the real ship. The successful test of a typical application scenario of the domestic ship hydrodynamics numerical software on the industrial cloud platform provides a powerful and controllable simulation tool for the study of ship navigation wave-making.

Key words: high performance numerical software, industrial cloud platform, ship hydrodynamics, ship navigation wave-making, engineering simulation
