Analýza betonových základových konstrukcí pomocí superpočítače a HPC

Abstract

Dissertation focuses on analysis of concrete foundations using a supercomputer and HPC. The dissertation deals with the topic on three levels, which complement each other and help to create a comprehensive view of the issue. The first part of the analysis focuses on the experimental testing and measuring deformations of soil-structure interaction performed at in-situ test. Analyzed data used to verify the numerical values. Numerical models of soil-structure interaction were created in second part of the analyses. Model was prepared in the form of a script in the Ansys APDL 18.0 program, which was tested and verified on a desktop computer on small tasks and run on a supercomputer. A parametric study that analyzes the influence of input parameters on the numerical results of the calculations was created. Influence of boundary conditions and size of the modeled area were also investigated. In the third part, the author established the abilities, possibilities and limitations of the supercomputer Anselm so even tasks demanding on computing time can be calculated in civil engineering practice. HPC capabilities on the Anselm supercomputer at the VŠB-TUO campus using the Ansys computing program were used when creating simulation task. The model was prepared in the form of a script. Maximum task size and resource allocation were determined.
