Using the capabilities of standard application software in solving an engineering problem

The article describes the software implementation of the solution of an engineering problem.The task was to use the capabilities of standard application software to create a simulation program for changing the water level in a tank of the correct shape when a hole appears. The article justified the choice of software, described solutions to the direct and inverse problems.The software implementation developed by the authors is successfully used in the production processes of the «Astana-Energia» JSC Power Unit.
