WEB IMPLEMENTATION THE POSTPROCESSOR WITH AN OPEN-SOURCE CODE

The paper considers one of the most promising areas for increasing the efficiency of designing modern equipment, namely, creating a tool for conducting a virtual computer experiment instead of full-scale tests, which significantly speeds up and reduces the cost of the development process, as well as ensuring its greater safety.Most often in practice, the numerical finite element method is used for computer modeling of a wide range of problems. Its application requires the availability of specialized software – finite element analysis systems, which can be conditionally divided into three main subsystems: 1) preprocessor (data preparation for calculation),2) processor (calculation implementation) and 3) postprocessor (results analysis).Practical experience shows that the stage of results analysis (postprocessing) in terms of its complexity and duration can significantly exceed the two previous stages of numerical modeling. That is why the efficiency of automated design in mechanical engineering and construction directly depends on the quality of the implementation of the postprocessor and the convenience of its use by the user.The vast majority of modern postprocessors are integral components of the corresponding finite element analysis systems (for example, Ansys, MSC Nastran, COMSOL, etc.). This actually makes it impossible to use them together with third- party systems focused on solving certain narrow classes of problems (for example, composite mechanics). In addition, cloud technologies have been developing rapidly recently, which requires the creation of appropriate software, the implementation of which in the form of web applications will allow achieving real cross platform, since modern browsers are actually hardware-independent virtual machines that run on almost all types of modern computer technology. That is why the development of separate software systems for automating post-analysis of the results of numerical calculations obtained in various numerical modeling systems in the form of open-source web applications is currently an urgent task.
