Abstract

The invention relates to the technical field of explosion damage assessment, in particular to a Tianhe supercomputer-based city explosion damage effect assessment method. The method comprises the steps of extracting typical analysis characteristics of city buildings through a BIM; establishing and solving a setting rule according to a simulation model; developing modeling and solving display programs on a simulation software platform and a Tianhe supercomputer platform; realizing automatic simulation model building, solving calculation and display function customization; and realizing city explosion damage effect assessment. According to the method, large-scale and high-precision multi-task parallel calculation of the complex simulation model can be performed based on a Tianhe-1 supercomputer, so that the calculation cycle is shortened; by virtue of the BIM, accurate city geometric information can be quickly extracted, and a corresponding geometric model is generated according to analysis needs; and based on this, a simulation solving model is automatically built according to the analysis needs, and corresponding software and hardware resources are matched, so that the time for adjusting the model by personnel is shortened and relatively good calculation configuration is achieved.

Description

technical field [0001] The invention relates to the technical field of explosion damage evaluation, in particular to a method for evaluating urban explosion damage effects based on Tianhe supercomputer. Background technique [0002] Tianhe-1 supercomputer is my country's first petascale supercomputer. It ranked first in the world's supercomputer TOP500 ranking in November 2010, marking that the comprehensive technical level of my country's self-developed supercomputer has entered the world's leading ranks. The development of BIM (Building Information Modeling) technology has made it possible to accurately and accurately record the building information of buildings and cities. Based on it, a variety of applications can be carried out, such as construction simulation, operation and maintenance, virtual roaming, etc. At present, the Tianhe BIM cloud system has been deployed on the Tianhe supercomputing platform to carry out related development and application in the field of BI...

AI Technical Summary

Problems solved by technology

At present, there are mainly the following deficiencies in the evaluation of explosion damage effects: 1) Due to the limitations of software and hardware equipment, most damage evaluation calculation scales are generally small, and the model has been simplified to a large extent, resulting in low evaluation results; 2) The explosion calculation of urban building complexes involves many and complex calculation structures, so the actual calculation is more about rough modeling, and the building model is built by a method similar to building blocks, with less consideration of details; 3) Traditional calculations require continuous manual 4) There is no automatic solution setting, which makes it trapped in the complicated work of model solution
