The problem is this ---- "Error: DET<0" in the 1 phase
the answer from faq on plaxis site is
=====This error in iterative solver can be caused by:
*1- Not enough memory (or too many elements for the current memory)
* 2- Badly shaped elements: good elements are those with the same size for width, length and height of the element.
*3- Large stiffness differences in your model (e.g. a difference ratio > 1E6). This also includes the use of structures (beams, walls)
So please check your mesh (both 2D and 3D) in detail, and check if you use large stiffness differences in the used materials. Sometimes a hint is given by the program: if you e.g. activate a plate in phase 4, and this phase shows the error, it is likely that the used stiffness for the plate is too high for the numerical model.======
for *1 i have 4gb ram
for *2 all the piles have the same size
for *3----well this is the problem...i do not fully understant want they want to say.......i use this pb for about 2 weeks so i am new at this......
maybe someone can help me with an answer or to resolve the problem
i have atached the work files
thank you in advance

hi anyone could upload revit extensions 2011 that works perfectly with windows 7 although it install no problem in other features of the extensions but RS2011 going to ASD 2011 the extension does not detect ASD2011 or if the problem was in ASD 2011 could somebody advice me what to do to fix the issue regards on the compatibility of ASD 2011 in windows 7
GIS for Water Resources and Watershed Management
Edited by John G. Lyon
Publishers: Taylor & Francis (London & New York)
No. of Pages: 274
Binding: Hardcover
Language: English
Published year: 2003

The use of GIS, and its application for solving environmental problems is growing rapidly. This powerful set of tools can be used to great effect in hydrological modeling, environment and habitat assessments, ecosystem studies, monitoring of wetlands and forested watersheds, urban studies, agricultural impact assessment and much more. GIS for Watershed and Water Resource Management explains the fundamentals, demonstrates new approaches, techniques and methods, and provides examples of real applications. It presents the basic concepts, and shows how to acquire the critical information needed to plan and implement GIS studies, and develop practical solutions for environmental management and problem solving.

GroundWater Modeling using Geological Information System
Writer: George F. Pinder
Publisher: John Wiley & Sons, Inc., USA
Published Year: July 2002
Language: English
ISBN: 9780471084983
Hardcover
248 pages
Book Info:
Groundwater Modeling Using Geographical Information Systems covers fundamental information on flow and mass transport modeling and demonstrates how GIS technology makes these models and analyses more accurate than ever before.
GIS technology allows for swift organization, quantification, and interpretation of large quantities of geohydrological data with computer accuracy and minimal risk of human error. This book's companion Web site provides the Princeton Transport Code, as well as the plug-in extensions required to interface this code with the Argus ONE numerical environment software enclosed with this book. Plug-in extensions for MODFLOW and MT3D computer codes can be found at the Argus ONE Web site (ww.argusint.com). The process for using the Geographic Modeling Approach (GMA) to model groundwater flow and transport is demonstrated step by step with a field example from Tucson, Arizona. The GMA is composed of the Argus ONE Geographic Information Modeling system and the Princeton Transport Code groundwater flow and transport model, interfaced through the plug-in extension available on Argus ONE.
Enhanced with more than 150 illustrations and screen captures, Groundwater Modeling Using Geographical Information Systems is a fundamental book for civil engineers, hydrologists, environmental engineers, geologists, and students in these fields, as well as software engineers working on GIS applications and environmental attorneys and regulators. When used in combination with the free modeling software, this book provides an excellent student text.
