Finite Elements Method and its Space Application in the Study of Movements of GNSS BULiPOS Reference Stations in Bulgaria Keranka VASSILEVA 1, Georgi VALEV 2, Bulgaria 1 National Institute of Geophysics, Geodesy and Geography Bulgarian Academy of Sciences 2 University of Architecture, Civil Engineering and Geodesy. Numerical visualization is carried out in the freeware FEPlot used before for the FEM and FDM output files and procedures. FINITE ELEMENT METHOD 5 1. The ordinary finite difference method is used to solve the governing differential equation of the plate deflection. "A Large Displacement Finite Element Analysis of a Reinforced Unpaved Road" of Materials in Civil Engineering" abstract Averaging and its Application in Wind. The finite difference method for the two-point boundary value problem. SAP2000 is general-purpose civil-engineering software ideal for the analysis and design of any type of structural system. The resulting partial differential equation is solved by the boundary element method at each time step.
