Introduction

Numerical box 3D is a highperformance numerical computing system with completely independent theoretical basis and independent intellectual property rights.

A new discrete numerical calculation method of rock dynamics, distinct lattice spring model (dlsm), is provided.

And the first numerical calculation theory using parallel world hypothesis, four dimensional lattice spring model (4d-lsm).


Abilities
Problem solved
Application scenarios
Based on rock mechanics, the Poisson's ratio constraint of LSM method is overcome
The historical bottleneck of material nonlinear characterization of LSM is solved
For its from the laboratory to field engineering applications cleared obstacles
Thermal damage of geothermal reservoir
Propagation of explosion wave
Laser assisted rock breaking
Crack propagation of rock fracture
Large deformation analysis of roadway/tunnel
Foundation pit supporting
Based on the characteristics of DLSM proposed by ourselves and variable decomposition, a solution framework is established that can connect the traditional continuum constitutive model to DLSM, and realize DLSM transplantation of the classical uncorrelated DP elastic-plastic theory. It is found that the nonlinear representation problem of LSM is enhanced, and the fracture solution advantage of LSM is retained. The successful prediction of plastic fracture of titanium alloy was published in the authoritative peer-reviewed journal of computational mechanics in Rock and soil, Compuy.geotech.

The transplantation of 4D-LSM and DLSM on "Tianhe-3 E-class prototype" supercomputing cluster in National Supercomputing Center tianjin was realized
Using 600 cpus, we successfully performed a very large scale computation of 1 billion numerical cells
It is the world's largest discrete numerical model for rock dynamics engineering problems
It was selected as the independent software project of National Supercomputing Tianjin Center
