Abstract:
This study considers using of Component Template Library (CTL) as middle-ware and weak coupling algorithm of software components for heat transfer and structure analysis. The CTL interface is specially designed to exchange data between the software components. The structure simulation component is linked to the heat transfer simulation component by remote method invocation and by dynamic linkage. The simulation of welding procedure with the moving heat source was used to describe how the proposed procedure works. The heat transfer component computes changes of temperature at all nodes for given values of heat source and the structure analysis component computes the strains induced by the temperature changes in each time step. The CTL interface provides transfer of data between communication points into the component codes. The requirements for the simulation interface and software architecture are given and analyzed. Using the CTL as middle-ware, the coupling of software components in partitioned formulation becomes satisfying solution for such simulations.
