STATIC AND DYNAMIC 2-DIMENSIONAL FINITE ELEMENT ANALYSIS OF CONTINUA  

VERSAT-2D is a software package consisting of three computer programs, namely, VERSAT-2D Processor, VERSAT-S2D and VERSAT-D2D.  VERSAT-2D Processor is a Windows based graphic interface program.  It serves as a pre and post processor for VERSAT-S2D and VERSAT-D2D.  The program is used to generate a finite element mesh, define soil zones, assign material properties, define boundary conditions, assign pressure loads, and generate input data for VERSAT-S2D & VERSAT-D2D. VERSAT-S2D is a computer program for static 2D plane-strain finite element analyses of stresses, deformations, and soil-structure interactions.  VERSAT-D2D is a computer program for dynamic 2D plane-strain finite element analyses of earth structures subjected to dynamic loads from earthquakes, machine vibration, waves or ice actions......VERSAT-2D 2010 Free Trial Version

  DYNAMIC 3D FINITE ELEMENT ANALYSIS OF SINGLE PILES AND PILE GROUPS      

VERSAT-P3D is a finite element program for quasi-3D nonlinear dynamic analyses of single piles and pile groups in frequency and time domain (Wu and Finn, 1997, Canadian Geotechnical Journal 34: 34-52). The frequency-domain analysis is used to determine dynamic stiffness and damping as a function of vibration frequency, and to compute moment and shear response of piles subjected to loading at the pile top or at the cap of a pile group. Dynamic time-domain analysis is used to directly compute pile response to seismic loading and therefore allow direct determination of the time-dependent stiffness variation of single piles or pile groups....VERSAT-P3D 2006 Free Trial

 GEO-COMPUTING LIBRARY^(new):  Limitation of Liability for Applications in the Geotechnical Calculation Library      

Although the geotechnical calculations have been tested extensively by the publisher and experience of using it would indicate it is accurate within the limits given by the assumptions of the theory and data used, the publisher (Wutec Geotechnical International) and the author (G. Wu) assume no liability whatsoever with respect to any use of this software or with respect to any damages or losses that may result from such use.  Any use of this software to solve problems is the sole responsibility of the user as to whether the output is correct or correctly interpreted or the problem correctly modelled.
