Method and device for realizing calculation tasks of ls-dyna

Abstract

The present invention discloses a method and device for realizing calculation tasks of LS-DYNA, wherein the realization method includes: obtaining calculation instructions input by users; analyzing the calculation instructions, determining the type of calculation and the calculation parameters contained in the calculation instructions ; Substituting the calculation parameters into the pre-configured calculation command statement corresponding to the calculation type, and executing the calculation command statement. With the help of the technical solution of the present invention, the realization process of the calculation task of LS-DYNA can be realized without using the command line, and the calculation task can be completed only through the simple operation based on the graphical interface, which greatly reduces the difficulty of operation, improves the execution efficiency, and reduces the error probability.

Description

Technical field [0001] The present invention relates to the field of scientific computing, and in particular, to a method and device for implementing LS-DYNA computing tasks. Background technique [0002] LS-DYNA is a well-known general-purpose explicit dynamic analysis program that can simulate various complex problems in the real world. It is especially suitable for solving various nonlinear dynamic impact problems such as high-speed collisions, explosions and metal forming of various two-dimensional and three-dimensional nonlinear structures. At the same time, it can solve heat transfer, fluid and fluid-solid coupling problems, and is widely recognized as the best analysis software package in the engineering application field. [0003] In a traditional high-performance computing cluster environment, users who want to run LS-DYNA-based computing programs usually need to use a remote character terminal to perform a series of operations in a command line environment. Generally, the...
