CREATING AND USING DYNAMIC LINK LIBRARIES IN ENGINEERING CALCULATIONS

The article describes creation and using of dynamic link libraries in technical calculation. Description of creation universal libraries is given, also it is spoken in detail about OpenMaple technology which can be used only with Maple package. In conclusion the authors write about advantages and disadvantages of calculation with own dynamic link library. Today there are many mathematical packages, such as Maple or Mathcad, which give many different tools for calculations. The main problem that these packages do not solve most engineering tasks. There are no good thermodynamic or thermophysical libraries which could give possibility do not use any other programs, such as Cool Pack or REFPROP. Actually, if there is necessity to design apparatus or to calculate thermodynamic cycle, it's necessary many time. The main problems are unwieldy and long calculations which cannot be automatized completely. One of the solutions that can help is creation of your own dynamic link library (dll). Dynamic libraries can be either universal or designed for a specific mathematical package. The OpenMaple technology allows to create own libraries for Maple. If you want to make library you should know C, Java or FORTRAN languages. This library could not be created directly in Maple. Traditionally, the basic development environments are Embarcadero C++ or Visual Studio. This technology still has both advantages and disadvantages.
