In this paper we discuss a number of results that were gained with the application of the UNICORE platform in a DiVTB system for creating virtual test beds. The DiVTB system provides a problem-oriented user interface to distributed computing resources within the grid, online launch of Computer-Aided Engineering (CAE) simulation, automated search, monitoring and allocation of computing resources for carrying out the virtual experiments. The studies were presented within the framework of the "Mobility of Young Scientists" project of The Federal Target Programme entitled as "Scientific and Scientific-Pedagogical Personnel of the Innovative Russia for the Years 2009-2013" in 2012.
