Введение. Одним из ключевых аспектов решения любых задач численными методами является интерпретация полученных результатов с целью их дальнейшего использования. Современные расчетные комплексы, реализующие метод конечных элементов, имеют в своем составе так называемый постпроцессор — модуль, предназначенный для облегчения визуализации и интерпретации результатов выполненных вычислений. Однако, каким бы продвинутым не был встроенный в программный комплекс постпроцессор, его функционал может быть недостаточен для решения конкретной инженерной задачи. Один из способов оптимизации соответствующих этапов работы — применение сторонних программных продуктов и разработка самописных пользовательских расширений.

Материалы и методы

Материалы и методы. Определение требуемых параметров армирования монолитных железобетонных конструкций сложной геометрической формы выполнено в вычислительном комплексе SCAD++, но дальнейшая их обработка встроенными средствами затруднительна. В рамках предложенной методики интерпретации и анализа полученных в SCAD++ результатов армирования монолитной железобетонной плиты с широкими балками применялись свободно распространяемый программный продукт Gmsh и пользовательский скрипт на языке программирования Python.

Результаты

Результаты. Реализация предложенного алгоритма обработки данных, полученных из SCAD++, позволила преодолеть ограничения стандартных средств проектно-вычислительного комплекса в части визуализации результатов выполненных расчетов, а также сформировать исходные сведения для их дальнейшего использования в процессе инженерно-строительного проектирования.

Выводы

Выводы. Предложенная методика удобна для применения в инженерной практике и предоставляет широкие возможности для эффективного анализа результатов расчетов, выполненных методом конечных элементов, и их дальнейшей обработки. Ее использование позволит повысить эффективность принимаемых решений, оптимизировать процесс проектирования геометрически сложных конструкций и их элементов, а также оптимизировать материальные затраты на приобретение программного обеспечения.

Introduction

Introduction. One of the crucial aspects of solving various mechanical problems using numerical methods is the interpretation of the obtained results for their further use. Modern computational complexes implementing the finite element method have a so-called postprocessor — a module designed to ease visualization and interpretation of the results of performed calculations. However, no matter how advanced the postprocessor built into the CAE programme is, its functionality may be insufficient for solving a particular engineering task. One of the ways to optimize the relevant stages of work is to use third-party software products and develop custom extensions.

Materials and methods

Materials and methods. Determination of the required parameters of reinforcement of monolithic reinforced concrete structures of complex geometric shape is performed in the SCAD++ computer complex, but their further processing by built-in tools is challenging. Within the framework of the proposed methodology, interpretation, and analysis of the results of reinforcement of a monolithic reinforced concrete slab with wide beams obtained in SCAD++ were performed using the freeware software product Gmsh and a user script in the Python programming language.

Results

Results. The implementation of the proposed algorithm of data processing obtained from SCAD++ allowed to overcome the limitations of standard means of CAE system in terms of visualization of the results of the performed calculations. As well as to create initial data for their further use in engineering and construction design.

Conclusions

Conclusions. The proposed methodology is convenient for application in engineering practice and provides wide opportunities for effective analysis of the results of calculations performed by the finite element method and their further processing. Its use will increase the efficiency of decisions taken, improve the design process of geometrically complex structures and their elements, as well as optimize the financial costs of software acquisition.
