3. PAK-P A Finite Element 2D and 3D Program for Analysis of Groundwater Seepage  Linear and nonlinear analysis: steady, time- dependent problems  Saturated/unsaturated flow  Position of free surface  Boundary conditions: prescribed head, pressure, seepage face  Infiltration: special treatment of rain

4.  Special algorithm for nodes at seepage face  Material characteristics: Variable conductivity for unsaturated soil region  Seepage forces: Calculation of nodal forces due to fluid flow, generated in the format for FE structure program

5. PAK-C Finite Element Program For Coupled Problems – Multiphase Fluid Flow with Heat Transfer Through Porous Deformable Medium  Linear and Geometrically and Materially Analysis, Linear and nonlinear solid, stationary and nonstationary, compressible and incompressible fluid  Static and Dynamic Analysis  Material Characteristics: Variation of porosity, elastic and elastoplastic consolidation, elastic, elastoplastic Cam- clay, thermoelastic material models, modelling of subsidence  Heat transfer and fluid flow  Multiphase flow
