    The topic of the following thesis was to create a program that allows to analyze the quality of modeling wave field depending on the applied boundary conditions. The program implementing acoustic wave field modeling using finite difference method has been developed based on the Java programming language using design patterns to enable further development of application. Document includes description of the issues related to the modeling of the propagation wave field, with particular emphasis on finite difference method and the theoretical description of the boundary conditions. Thesis includes also specifications of methodology of research and application that allowed implementation of calculation model. The last part of it is to present and analyze the results of research.

    The aim of this thesis is to define differences occurred on model's bounds after use boundary conditions for values of wavefield considering various differential sachems. Differential schemes of 2nd and 4th order was determined with using two the most common boundary conditions: absorbing and reflective bound. Software written by author was used for modelling wavefield. Program has a window interface which allows to submit desired geological model based on velocity of wave in various environments. For check and comparison differences in results MatLab software was used. The conclusion was built on analyses of received data.

    Wykorzystanie submodelingu do modelowania zachowania się budowli poddanej wpływom eksploatacji
    (2007) Tajduś, Krzysztof; Tajduś, Antoni
    This paper describes the correct selections of the bonduary conditions, of the models presents the influence of the underground excavations on the bulding based on FEM. The authors incline to solve this problem by using the dobblepart methods, based on global model and sub-model. In this technic the boundary conditions of the sub-model are the value of vertical and horizontal displacements calculate previously in global model. Aditionally the authors made some calculations of the influence of the size of the model bedrock of the stress values in the fundations based on it.
